Libraries house thousands of print materials, not to mention all the information that is accessible online, such as books, magazines, movies, etc. Because there are so many, it would be impossible to find anything if they weren't organized at all. To make everything easy to find and browse too, several different classification systems have been developed that are used all over the world. The SUU Sherratt Library uses both Library of Congress and the Dewey Decimal systems- Library of Congress Classification is used for the main collection and everything else except the Juvenile and Curriculum collections on the 3rd floor, which are better suited to Dewey.

Note for INFO 1010:

Knowing how to find books and materials in the library is important, especially as you start collecting books to use in your ENGL 2010 papers. In the Module 4 assignment, you will be asked to find a book as well as popular and scholarly articles. If you choose to use the book for the in class portion of the assignment (for those of you in the face to face sections co-rec'd with ENGL 2010), you will need to physically bring the book in as well- which is another reason to know how Library of Congress Classification works.

Library of Congress and Dewey Classification Systems

Section three a: find books and articles - finding books and media - library of congress and dewey decimal classification systems, ​library of congress classification system.

The Library of Congress Classification System is used in most college and university libraries. In the Sherratt Library, the LC system is used in all collections except the Curriculum and the Juvenile Collections on the Third floor, which use the Dewey Decimal Classification System . The DDC is used in school, public, and small libraries.

In 1899, the United States Library of Congress created a classification scheme for books. It is called the Library of Congress Classification system (LC for short). In this system, all knowledge is divided into 21 broad subject areas by letters of the alphabet (I, O, W, X, and Y are not used). There is no significance for the letters of the alphabet chosen for each broad subject area. There is no need to memorize this classification system, but it is helpful to know how it works.

Here's an outline of the major subject areas in the LC system :

A second letter is then used to further subdivide subject areas. For example, the "G" subject category is divided into these subdivisions:

Each subject subdivision is then further divided into specific topics using numbers. This combination of subject areas (letters) and numbers is called the call number for that book. 

Dewey Decimal Classification

The Dewey Decimal Classification system is used for the Curriculum and Juvenile Collections . These book collections are used mainly by education students. This system uses numbers to group books by subject:

Dewey works very similarly to Library of Congress, but it starts with numbers instead and is grouped into a smaller number of broader subjects. This makes it much more suitable to Juvenile Collections rather than the much larger amount of subjects at university libraries. You will definitely see Dewey being used often in Public Libraries as well.

Finding Books in the Library

Call numbers.

A call number begins with one or two letters. The call number for the book shown here is:  GV 989 .A52 

Shelf Order

Books are placed on shelves according to their call numbers. Books are shelved from left to right according to the LC system. Books are arranged first by the alphabetical top row, then by the number in the second row, finally by the alphabetical letter and decimal number in the third row:

books classification in the library

So GA goes before GV, and just G would go before GA. The 989 is a whole number, so look at it in completion, with 99 being smaller than 989.

Remember, when using decimal numbers, numbers will be smaller to larger, left to right! (For example, when comparing .A4010 with .A52 by position, the 4 is smaller than 5 so .A4010 comes first.)

If you understand how the LC system works in the Sherratt Library, you'll be able to walk into the Marriott Library at the University of Utah, or the Harold B. Lee Library at Brigham Young University, or the Widener Library at Harvard University and find books!

Collection Codes

Collection codes are identifiers added at the beginning of the call number to indicate a particular collection:

Locating books

books classification in the library

Call Number

Availability for checkout

With this information, you can go to that collection, and to the shelf where it is located.  For example, suppose you want to find the book  Roughing It , written by  Mark Twain . It is in the  Main Collection  on the  Second floo r, call  number  PS  1318 .A1 

As you move through the book shelves, check the signs on the wooden ends of the  shelves. Notice that the call number falls within the range of the shelf in this picture.

As you go down this aisle, look at the spine labels on the books. You see there are several books labeled  PS 1318 . Then look for the . A1  portion of the call number. Notice that there are other books on this shelf authored by Mark Twain.

TIP: Once you find an item on the shelf, browse items nearby. Books are shelved according to subject, and you may find something else useful. 

What if a book is missing?

If the library catalog   indicates that an item is checked in but you cannot find it on the shelf, follow these steps:

Double-check the collection and call number.

Look on nearby shelves to see if the item has been incorrectly shelved.

Look on the red return shelves near the area.

Ask someone at the Circulation Desk if the item is on a re-shelving cart.

Hint: When you take an item off the shelf, don't put it back yourself. Instead, put it on a red shelf so that a librarian can make sure it is returned to its correct location.

Reciprocal borrowing

As a student at SUU, you can use your SUU ID to borrow books from other academic libraries in Utah.

Elements of Cataloging and Classification

To "catalog" a book or other form of library material involves several interrelated processes which all contribute to the achievement of Charles Ammi Cutter's "objects" for a catalog:

  • To enable a person to find a book of which the author, title, or subject is known
  • To show what the library has by a given author, on a given subject, or in a given kind of literature, and
  • To assist in the choice of a book.

(Adapted Rules for a Printed Dictionary Catalogue, by Charles Ammi Cutter, 4th ed., 1904, p. 12.)

Thus, catalogers prepare a description of an item, assign subject headings, determine a shelf location using a classification system, provide a link to the electronic item, if appropriate, and code that information with both MARC tags or metadata so that it may be displayed in local online catalogs and, if the library catalogs with OCLC, in WorldCat. Each element of the cataloging process is addressed in other tabs of this Guide, along with sources for the cataloging tools needed.

General Bibliography

books classification in the library

Cataloging and Classification

The fourth edition of the late Lois Mai Chan's classic Cataloging and Classification covers the analysis and representation of methods used in describing, organizing, and providing access to resources made available in or through libraries. Since the last edition published in 2007, there have been dramatic changes in cataloging systems from the Library of Congress. The most notable being the shift from AACR2 to Resource Description and Access (RDA) as the new standard developed by the Library of Congress.

What is the Classification System

Good question! A library classification system is the way that books, videos, and other items are put in order on the shelf. In other words, it is how we find the things we have in the library.

Try as libraries may to make things easy, the library's classification system can be confusing. This is just a quick guide to explain the way items are shelved in the library.

If you still can't find what you are looking for, ask a librarian! Use the Get Help! tab to find out how to contact one.

Library of Congress Classification System: Home

Library of congress (lc) classification system.

Alliant Libraries http://library.alliant.edu

Books in most academic libraries are arranged on the shelves according to the Library of Congress (LC) Classification System. The LC system groups books into 21 broad subject categories which are identified by a letter of the alphabet.The subject categories are further subdivided into double letter or triple letter, detailed subject categories. The specific subject for each book is defined by the number following the first letters.

Example of first part of the call number:

The "B" classification includes books about philosophy, logic, psychology, mythology, aesthetics, and religion. BF is the subdivision for books about psychology. The call numbers in the range BF698-BF698.9 are reserved for books on personality. BF1001-1389 are call numbers reserved for books on parapsychology.

The second part of the call number consists of a single capital letter followed by one digit or more. This usually, but not always, represents the author's name, and is called the "Cutter" number. By putting the Cutter numbers in order within any particular subject call number, the books are arranged alphabetically by author.

A Cutter number may or may not be proceeded by a period on the spine label. Even if the Cutter number is not preceeded by a period you should assume it to be there. The imaginary period is very important in relation to finding materials on the shelves. The period should be treated like a decimal point.   These books would be located in this order on the shelf. If the third line of the call number is the same on two or more books use the fourth line to determine the order and location.

The call numbers would be read and shelved as:

BF 175 E3 A8 would come after BF 175 E294 1999 and not before since .294 is smaller than .300.

The final line on the call number is usually the year of publication. The spine label may also include a volume number. Reference books may have "REF" above the call number.

A more detailed outline of the LC Classfication system is located on the Library of Congress website at http://www.loc.gov/catdir/cpso/lcco/

If you have trouble finding a book in the library, please ask for assistance.

53 Bibliographic Classification

Much of our thinking about classification comes from the bibliographic domain. Libraries and the classification systems for the resources they contain have been evolving for millennia, shaped by the intellectual, social, and technological conditions of the societies that created them. As early as the third millennium BCE, there were enough written documents—papyrus scrolls or clay tablets—that the need arose to organize them. Some of the first attempts, by Mesopotamian scribes, were simple lists of documents in no particular order. The ancient Greeks, Romans, and Chinese created more principled systems, both sorting works by features such as language and alphabetical order, and placing them into semantically significant categories such as topic or genre. Medieval European libraries were tightly focused on Christian theology, but as secular books and readers proliferated thanks to new technologies and increased literacy, bibliographic classifications grew broader and more complex to accommodate them. Modern classification systems are highly nuanced systems designed to encompass all knowledge; however, they retain some of the same features and biases of their forebears. [1]

We will briefly describe the most important systems for bibliographic classification, especially the Dewey Decimal Classification (DDC) and Library of Congress Classification (LCC) systems. However, there are several important ways in which bibliographic classification is distinctive and we will discuss those first:

Department stores and supermarkets typically offer tens of thousands of different items (as measured by the number of “ stock keeping units ” or SKU s), and popular online commerce sites like Amazon.com and eBay are of similar scale. However, the standard product classification system for supermarkets has only about 300 categories. [2] The classifications for online stores are typically deeper than those for physical stores, but they are highly idiosyncratic and non-standard. In contrast, scores of university libraries have five million or more distinct items in their collections, and they almost all use the same standard bibliographic classification system that has about 300,000 distinct categories. [3]

A corollary to the previous one that distinguishes bibliographic classification systems is that they have long been shaped and continue to be shaped by the legacy of physical arrangement, user access to the storage locations, and re-shelving that they support. These requirements constrain the evolution and extensibility of bibliographic classifications, making them less able to keep pace with changing concepts and new bodies of knowledge. Amazon classifies the products it sells in huge warehouses, but its customers do not have to pick out their purchases there, and most goods never return to the warehouse. Amazon can add new product categories and manage the resources in warehouses far more easily than libraries can.

With digital libraries, constraints of scale and physical arrangement are substantially eliminated, because the storage location is hidden from the user and the resources do not need to be returned and re-shelved. However, when users can search the entire content of the library, as they have learned to expect from the web, they are less likely to use the bibliographic classification systems that have painstakingly been applied to the library’s resources.

The Dewey Decimal Classification

The Dewey Decimal Classification (DDC) is the world’s most widely used bibliographic system, applied to books in over 200,000 libraries in 135 countries. It is a proprietary and de facto standard, and it must be licensed for use from the Online Computer Library Center (OCLC) . [4]

In 1876 , Melvil Dewey invented the DDC when he was hired to manage the Amherst College library immediately after graduating. Dewey was inspired by Bacon’s attempt to create a universal classification for all knowledge and considered the DDC as a numerical overlay on Bacon with 10 main classes, each divided into 10 more, and so on. Despite his explicit rejection of literary warrant, however, Dewey’s classification was strongly influenced by the existing Amherst collection, which reflected Amherst’s focus on the time on the “ education of indigent young men of piety and talents for the Christian ministry. ” [5]

The resulting nineteenth-century Western bias in the DDC ’s classification of religion seems almost startling today, where it persists in the 23 rd revision (see Figure: “ Religion ” in Dewey Decimal Classification. ) . “ Religion ” is one of the 10 main classes, the 200 class, with nine subclasses, Six of these nine subclasses are topics with “ Christian ” in the name; one class is for the Bible alone; and another section is entitled “ Natural theology. ” Everything else related to the world’s many religions is lumped under 290, “ Other religions. ”

The notational simplicity of a decimal system makes the DDC easy to use and easy to subdivide existing categories, So-called subdivision tables allow facets for language, geography or format to be added to many classes, making the classification more specific. But the overall system is not very hospitable to new areas of knowledge.

The Library of Congress Classification

The US Library of Congress is the largest library in the world today, but it got off to a bad start after being established in 1800 . In 1814 , during the War of 1812 , British troops burned down the US Capitol building where the library was located and the 3000 books in the collection went up in flames. [6] The library was restarted a year later when Congress purchased the personal library of former president Thomas Jefferson , which was over twice the size of the collection that the British burned. Jefferson was a deeply intellectual person, and unlike the narrow historical and legal collection of the original library, Jefferson’s library reflected his “ comprehensive interests in philosophy, history, geography, science, and literature, as well as political and legal treatises. ” [7]

Restarting the Library of Congress around Jefferson’s personal collection and classification had an interesting implication. When Herbert Putnam formally created the Library of Congress Classification ( LCC ) in 1897 , he meant it not as a way to organize all the world’s knowledge, but to provide a practical way to organize and later locate items within the Library of Congress ’s collection. However, despite Putnam’s commitment to literary warrant, the breadth of Jefferson’s collection made the LCC more intellectually ambitious than it might otherwise had been, and probably contributed to its dominant adoption in university libraries.

The LCC has 21 top-level categories, identified by letters instead of using numbers like the DDC (see Figure: Top Level Categories in the Library of Congress Classification. ) . Each top-level category is divided into about 10-20 subclasses, each of which is further subdivided. The complete LCC and supporting information takes up 41 printed volumes.

Bias is apparent in the LCC as it is in the DDC , but is somewhat more subtle. A library for the US emphasizes its own history. “ Naval science ” was vastly more important in the 1800s when it was given its own top level category, separated from other resources about “ Military science ” (which had a subclass for “ Cavalry ”). [8]

The LCC is highly enumerative, and along with the uniqueness principle, this creates distortions over time and sometimes requires contortions to incorporate new disciplines. For example, it might seem odd today that a discipline as broad and important as computer science does not have its own second level category under the Q category of science, but because computer science was first taught in math departments, the LCC has it as the QA76 subclass of mathematics, which is QA . [9]

The BISAC Classification

A very different approach to bibliographic classification is represented in the Book Industry Standards Advisory Committee classification (BISAC) . BISAC is developed by the Book Industry Study Group (BISG) , a non-profit industry association that “ develops, maintains, and promotes standards and best practices that enable the book industry to conduct business more efficiently. ” The BISAC classification system is used by many of the major businesses within the North American book industry, including Amazon , Baker & Taylor , Barnes & Noble , Bookscan , Booksense , Bowker , Indigo , Ingram and most major publishers. [10]

The BISAC classifications are used by publishers to suggest to booksellers how a book should be classified in physical and online bookstores. Because of its commercial and consumer focus, BISAC follows a principle of use warrant, and its categories are biased toward common language usage and popular culture. Some top-level BISAC categories, including Law, Medicine, Music, and Philosophy, are also top-level categories in the LCC . However, BISAC also has top-level categories for Comics & Graphic Novels. Cooking, Pets, and True Crime.

The differences between BISAC and the LCC are understandable because they are used for completely different purposes and generally have little need to come into contact. This changed in 2004 , when Google began its ambitious project to digitize the majority of the world’s books. (See the sidebar, What Is a Library? ) . To the dismay of many people in the library and academic community, Google initially classified books using BISAC rather than the LCC . [11]

In addition, some new public libraries have adopted BISAC rather than the DDC because they feel the former makes the library friendlier to its users. Some librarians believe that their online catalogs need to be more like web search engines, so a less precise classification that uses more familiar category terms seems like a good choice. [12]

One of the earliest known libraries—at Nippur in Mesopotamia—was small enough that its catalog needed no particular organization: the list of titles in the collection fit onto two easily scanned clay tablets. As collections grew, scribes made it easier to browse the contents of a collection by adding “ colophons, ” brief descriptions containing a document’s title, author, and place in a sequence of tablets (Casson 2002) . A further step was the sorting of works into categories. A temple in the ancient Egyptian city of Edfu placed books into different trunks based on their topics, including royal duties, temple management, and timekeeping, as well as two trunks each for astronomy and protection from crocodiles. The fabled library of Alexandria in ancient Greece used categories based on Aristotle’s three modes of thought: theoretical (e.g. mathematics, physics, metaphysics), practical (ethics, politics, economics), and poetic (poetry, music, and art), plus a fourth “ meta-category, ” logic, that applied to all of them. Callimachus , one of the library’s directors, created the Pinakes, a library catalog whose top-level distinction was between poetry and prose (followed by genre, author, and work). A few centuries later, librarians in the Chinese Wei and Jin dynasties (third-fifth centuries CE) settled on four major categories—classics, philosophy, history, and literature—that lasted well into the twentieth century. (Shamurin 1955) Unlike the Greek system, which classified authors, the Chinese system classified individual works; some authors have suggested that this reflects Western cultures’ greater emphasis on the individual. Medieval libraries adapted ancient practices for their own needs: monastery libraries had separate cabinets for topics such as Bibles, Church history, and Christian poets, and divided their collections into Christian and secular literature (meanwhile, scholars in the intellectually flourishing Muslim world classified knowledge into Muslim and non-Muslim sciences) (Christ 1984) . Today’s classification systems reflect both their debt to earlier systems and the biases of their own cultures: the first category of the Universal Decimal Classification, just like Aristotle’s “ logic ” category, is a meta-category covering organization, documentation, and information science, while the first top-level category of the Chinese Classification System is “ Marxism, Leninism, Maoism, and Deng Xiaoping theory. ”

(Taylor and Joudrey 2009, Ch. 3) is a historical review of library classification. (Svenonius 2000) reviews the evolution of the theoretical foundations. (Kilgour 1998) focuses on the evolution of the book and the story of the co-evolution of libraries and classification comes along for the ride.

Supermarkets typically carry anywhere from 15,000 to 60,000 SKU s (depending on the size of the store), and may offer a service deli, a service bakery, and/or a pharmacy. 300 standard product categories ( http://www.fmi.org/research-resources/supermarket-facts ).

Dewey Decimal Classification: http://www.oclc.org/dewey/ .

https://www.amherst.edu/aboutamherst/history . Today Amherst is aggressively co-ed and secular.

That was not a typo. The “ War of 1812 ” lasted well into 1815 . The persistence of an inaccurate name for this war reflects its unique characteristics. Wars (in the English language) are generally named for the location of the fighting or the enemy being fought (the Mexican-American War, the Korean War, the Vietnam War, the Iraq War), or for a particular ideal or ambition (the Revolutionary War, the Civil War). The War of 1812 does not satisfy any of these naming conventions; the war was fought across a huge range of geography from eastern Canada to Louisiana, between a diverse range of groups from Canadians and Native American tribes, with national armies getting involved very late in the war. While nominally fought over freedom the seas, the war quickly morphed into one about territorial ambition in North America. Of course, if the world were a place where people could agree on naming standards for wars, it is likely we would no longer have wars. See http://en.wikipedia.org/wiki/List_of_wars_involving_the_United_States .

(Miksa 1984, p. 3) .

For additional examples, (Shirky 2005) .

Cognitive Science has an even harder time finding its proper place in the LCC because it emerged as the intersection of psychology, linguistics, computer science, and other disciplines. Cognitive science books can be found scattered throughout the LCC , with concentrations in BF , P , and QA .

The Book Industry Study Group (BISG) first and foremost is focused on resource description and classification as means to business ends; this purpose contrasts with goals of DDC or LOC . BISG classifications are used for barcodes and shipping labels to support supply chain and inventory management, marketing, and promotion activities. See http://www.bisg.org/ .

See (Pope and Holley 2011) , (Samuelson 2010) .

What some call the “ Perry Rebellion ” or the “ Dewey Dilemma ” began in 2007 when the new Perry Branch Library in Gilbert, Arizona opened with its books classified using the BISAC rather than Dewey classifications. (Fister 2009) . This is a highly inflamed controversy that pits advocates of customer service and usability against the library establishment, which despises the idea of turning to retailing as inspiration when designing and operating a library. Even if BISAC gets more widely adopted in public libraries it is unimaginable that it can be used in research libraries.

Criteria of book classification

Md. Ashikuzzaman

Book classification, a fundamental practice in organizing library collections, is the systematic framework that transforms the vast realm of literature into a navigable landscape. This process involves assigning codes or labels to books based on their subject matter, genre, or other identifying characteristics, facilitating their orderly arrangement on library shelves. Book classification streamlines information retrieval and provides users with a structured and intuitive way of navigating various titles. As an essential component of library science, book classification exemplifies the commitment to making knowledge accessible, ensuring patrons can embark on a seamless journey through the boundless expanse of human understanding.

1.1 What is Book Classification ?

1.2 criteria of book classification..

Book classification involves assigning codes or labels to books based on specific criteria, ensuring a systematic library collection organization. The criteria for book classification can vary depending on the classification system used, but some common factors include:

  • Subject Matter: One of the primary criteria for book classification is the subject matter or content of the book. Books are grouped based on their primary topics or themes. This helps users locate materials related to specific subjects in a particular library section.
  • Genre or Form: Some classification systems consider the genre or form of the book, such as fiction, non-fiction, poetry, or reference materials. This criterion helps distinguish between different types of literature and guides users to the sections that match their preferences.
  • Author: In certain classification systems, books may be arranged alphabetically by the author’s last name. This approach makes it easy for users specifically looking for works by a particular author.
  • Publication Date: Some libraries or classification systems organize books chronologically by publication date. This arrangement can be useful for researchers or users interested in the historical development of a subject.
  • Language: In multilingual libraries, books may be classified based on the language in which they are written. This helps users navigate collections in languages they are familiar with.
  • Geographical Region: For libraries focusing on geography or cultural studies, books may be classified based on their relevance to specific geographical regions or cultural contexts.
  • Audience or Reading Level: Books can be classified according to the target audience, such as children’s books, young adult literature, or adult fiction. Additionally, some classification systems differentiate books based on reading levels.
  • Format: The physical format of the book, such as hardcover, paperback, or electronic, can be a criterion for classification. This is particularly relevant in libraries that cater to different reading preferences.
  • Special Collections: Libraries may have special collections dedicated to rare books, manuscripts, or other unique materials. These items may be classified separately from the general collection based on their distinct characteristics.
  • Interdisciplinary Topics: Some classification systems allow for categorizing books that span multiple disciplines or subjects. This ensures that interdisciplinary works are appropriately represented in the library’s organizational structure.

Different libraries may prioritize and implement these criteria differently, depending on their collection’s nature and users’ needs. The chosen criteria play a crucial role in creating a logical and user-friendly arrangement of books within the library’s classification system.

Here are some of the most common book classification systems:

  • Dewey Decimal Classification (DDC): The Dewey Decimal Classification (DDC) system, devised by Melvil Dewey in 1876, stands as one of the most widely used and enduring classification systems in library science. Its brilliance lies in its simplicity and adaptability, providing a systematic framework for organizing library collections across many subjects. The DDC categorizes knowledge into ten main classes, each represented by a numerical range. These classes cover philosophy, social sciences, and natural sciences. Further subdivision occurs through a decimal notation, allowing for increasingly specific subject delineation. This hierarchical and numeric approach enables libraries to arrange books on the shelves in a logical and easily navigable manner, facilitating efficient resource discovery for library patrons. The Dewey Decimal Classification remains integral to library operations, embodying Dewey’s vision of accessible and organized knowledge for all.
  • Library of Congress Classification (LCC): The Library of Congress Classification (LCC) is a library classification system developed by the Library of Congress in the United States. It organizes the books in the Library of Congress and many other libraries worldwide. LCC is an enumerative classification system that lists all the classes in officially published schedules. The schedules are divided into 21 main classes, subclasses, and divisions. LCC is used by large research and academic libraries, while most public libraries and small academic libraries use the Dewey Decimal Classification system.
  • Universal Decimal Classification (UDC): The Universal Decimal Classification (UDC) is a library classification system developed by Paul Otlet and Henri La Fontaine in Belgium in 1905. It is used to organize books in libraries and information centers worldwide. UDC is a facetted classification system that allows for the expression of complex subjects by combining multiple concepts. UDC is also multilingual, which means it is available in over 40 languages.

Book classification systems are an important tool for libraries. They help organize books logically and consistently, making it easy for users to find the books they are looking for.

6 Classification and Cataloging

This section covers cataloging very broadly. If you would like more in-depth information about cataloging in libraries, look at our other textbook:  Cataloging with MARC, RDA, and Classification Systems.

Without a system of organization, specific information would be impossible to locate in a library. With this in mind, libraries organize and shelf items of the same subject content together. Successful organization systems enable users to find the precise information they are seeking.

Libraries in the United States use two main classification systems:

  • Dewey Decimal Classification System – The Dewey Decimal Classification System is generally used in public and school libraries.
  • Library of Congress Classification System – The Library of Congress Classification System is usually found in academic and special (research) libraries.

Dewey Decimal System

Since 1876 the Dewey Decimal Classification has been the basis of library organization. It was created for the purpose of arranging resources in a logical order using Arabic numerals. Knowledge is divided into ten classes, representing traditional academic disciplines. The intent of the ten classes was to cover the universe of knowledge.

Within the ten classes are subclasses which can also be subdivided to gain greater and greater specificity. Example: 700s = The Arts, 740 = Drawing and Decorative Arts, 748 = Glass, and 748.5 = Stained, painted, leaded, mosaic. Further divisions are possible after the decimal for more specificity. See the table below for the ten classes.

MAIN CLASSES

  • 000   Generalities
  • 100   Philosophy, parapsychology and occultism, psychology
  • 200   Religion
  • 300   Social Sciences
  • 400   Language
  • 500   Natural sciences and mathematics (Pure science)
  • 600   Technology (Applied Sciences)
  • 700   The Arts
  • 800   Literature and rhetoric
  • 900   Geography, history, and auxiliary disciplines

Library of Congress System

In the early 1900s, the Library of Congress in Washington, D.C. developed the Library of Congress Classification System. The new system was devised because it was felt that the Dewey Decimal Classification System was not flexible enough for the vast collections of the Library of Congress. As time passed, most U.S. research and academic libraries adopted this system.

With this system, knowledge is divided into twenty-one broad categories – labeled A-Z (omitting I, O, W, X, and Y). These categories are then subdivided by adding one or two additional letters and a set of numbers. This alpha-numeric system uses specific subclasses for a variety of the main classes. See the table below for the Library of Congress Classification classes.

  • A   General Works
  • B   Philosophy; Psychology and Religion
  • C   Auxiliary Sciences of History; Civilization
  • D  General and Old World History
  • E   History of North America
  • F   Local U.S. History. Canada. Latin America
  • G   Geography; Maps, Anthropology; Recreation
  • H   Social Sciences; Economics and Sociology
  • J    Political Science
  • K   Law (General)
  • L    Education
  • N   Fine Arts
  • P    Language and Literature
  • Q   Science
  • R   Medicine
  • S   Agriculture
  • T   Technology
  • U   Military Science
  • V   Naval Science
  • Z   Bibliography, Library Science, Information Resources

Theory, Practice, and Catalog Record Parts

In order to understand the current norms in the field of cataloging, you need to understand some more library history. AACR2 , or Anglo-American Cataloging Rules 2, was the accepted set of rules for catalogers for many years. However, it gradually become obsolete in the modern world of digital technology. Therefore, a team of librarians and other information professionals came together to create a new edition. Much like the Constitutional Convention of 1789, they ended up completely straying from that goal and the world is much better for it. The result of their series of meetings was RDA , or Resource Description and Access. It kept the same theoretical framework of AACR2, which was called FRBR , but it updated the terminology and policies to fit the Internet-based library. FRBR stands for Functional Requirements for Bibliographic Records and emphasizes the importance of placing an item in the context of its author, parent works, and other manifestations of the same work. This ensures that inaccurate records are kept at a minimum. RDA helps with ensuring that format, information medium type and other determining aspects of library items are recorded in a manner that is as accurate and standardized as possible.

MARC records were first developed in 1966 by the Library of Congress and have become the standard format for recording and sharing information about a bibliographic item. With the use of content designators (tags, subfield codes, and indicators), information is stored electronically and can be retrieved and interpreted by any other computer that is programmed to read MARC. This creation was the basis for the automation of library bibliographic records. Some of the most important MARC Fields are:

  • 010   LC card number
  • 050   Library of Congress Classification Number
  • 082   Dewey Decimal Classification Number
  • 100   Personal author main entry
  • 245   Title proper, subtitle, and statement of responsibility
  • 246   Variant form of title
  • 250   Edition statement
  • 260   Publication information
  • 300   Physical description
  • 440   Series
  • 500   General note
  • 505   Contents note
  • 650   Subject heading
  • 700   Personal author added entry

Item Identifiers in Catalog Records

One of the most important aspects of a catalog record is the identifiers of the item and those of related items. Identifiers tell record readers exactly where to find a particular resource. The modern library has four main types of identifiers.

ISBN : International Standard Book Number. This number is created by the publisher of a particular manifestation or expression of a work. ISBNs are not particular to an item, but you should still put them in catalog records so that users can verify what edition or version of an item they are receiving. The serial version of this identifier is ISSN .

URI : Uniform Resource Identifier. This a chain of characters that represent works and items. Originally, only online resources were given URIs. Now, though, some physical items have also been given URIs. A subgroup of URIs is the IRI, or Internationalized Resource Identifier, which allows for non-roman characters in identifiers. URLs are also a form of URI.

The most ubiquitous form of identification in a library record is the item Call Number . Every item in a library has a particular call number, even if it is as simple as BRDSD 1 for the first Broadside in an archival library collection. Different types of libraries have certain standards and procedures for creating a call number. Special libraries, like archives, for example, may only catalog collections of items or boxes of items in a collection rather than individual items. In fact, best practice in this type of library forbids item-by-item cataloging. In general, though, the other types of libraries either use the Dewey Decimal System or Library of Congress Classification System to produce a call number for each item in their collections.

Real-Life Examples

Let us see how libraries apply these concepts and options in real life. In order to understand how to provide effective services, you need some experience on the front end, the user-experience side, of the catalog or discovery service. In fact, unless you are a technical librarian the part of the discovery service you usually use will be the front end.

A system created by Melvil Dewey in the late nineteenth century to classify all knowledge into ten broad categories. This system has been modified twenty three times until the current iteration, Dewey Decimal System Edition 23, was created in early 2010s. It is often used on its own and in conjunction with the Library of Congress Classification System.

A system created by the Library of Congress to classify all information resources within its holdings. All items are classified in a broad category under each letter of the alphabet. Further letters and numbers create increasingly specific categories until the most appropriate category for each item is found. Unlike the Dewey Decimal System, which categorizes items by subject, the LCC classifies items by the discipline in which they can be used.

An acronym that stands for Anglo-American Cataloging Rules, Edition 2. This was the precursor to RDA, Resource Description and Access.

This acronym stands for Resource Description and Access. The successor to ACCR2, this schema provides the correct and precise methods and standardized entries for several MARC fields, including fields 336, 337, and 338.

Functional Requirements for Bibliographic Records. This is the theoretical framework that governs the presence, order, format, and other aspects of metadata contained in all records maintained by the library.

MAchine-Readable Catalog Record. This is the standard format for all item descriptions in a library's holdings. the vast majority of libraries use this system. Even those libraries that do not use MARC have adapted their systems from this type of record.

International Standard Book Number. This number is not the same as the call number and was created for a different purpose: commercial sales and proliferation data tracking. Publishers give each edition of a book a number. All items in a particular manifestation are given the same ISBN, and sometimes multiple manifestations are given the same ISBN.

International Standard Serial Number. This number is derived from the practice of using ISBNs for books. Every serial has its own ISSN, partly to distinguish from serials that have the same name or a similar name. Changing the name of a serial in a significant way will result in another ISSN being created, but there can be metadata notes to connect the two names.

Uniform Resource Identifier. In the context of digital items, a URI is a string of characters that belongs to an item and serves as its digital, machine-readable identifier. URIs are increasingly being used for real-world objects and items as well, in addition to works, expressions, and manifestations. URIs that refer to real-world objects are called Internationalized Resource Identifiers (IRIs). Every URI is an IRI. Also, every URL is a URI. A URL, as you know, points to a specific web page or website with increasing specificity as you go through the site hierarchy. A URI cannot be used for more than one item, and hierarchies of URIs can be used to demonstrate relationships in the FRBR schema and other schemata.

A number assigned to each item in the library that describes the precise physical and relational location of a book through association. In a less library-jargon way, it describes the location of a book in the order of all of the books.

The American Library Association Releases 'Book Résumés' for Banned Books

The American Library Association’s Unite Against Book Bans initiative has unveiled a new free resource—a collection of “book résumés.”

Created in collaboration with dozens of publishers, Unite Against Book Bans book résumés are easy-to-print documents that summarize a banned book’s significance and educational value, including a synopsis, reviews from professional journals, awards, accolades, and more. The book résumés also include information about how a title has been successfully retained in school districts in the face of demands to censor it. ALA officials said that the PDFs can be downloaded and printed for easy sharing with administrators, book review committees, and the public at local school and library board meetings.

“Unite Against Book Bans partners recognized a need for easy-to-access free resources for the many librarians, educators, and community advocates, who are working so hard to ensure that readers can always access an inclusive, diverse collection of books,” said Deborah Caldwell-Stone, director of the ALA’s Office for Intellectual Freedom, in a statement. “The work they’re doing—defending the freedom to read—is difficult and hard, and we want to make the task of gathering the information needed to do that easier.”

The book résumé program launched on February 20 with “hundreds” of documents available, with ALA reps noting that more will follow in time for National Library Week , to be held April 7–13. Despite a number of high-profile legal victories for freedom to read advocates in recent months, ALA said that its forthcoming book ban data, set to be released during National Library Week, will show anther significant increase in the number of titles targeted for censorship.

Unite Against Book Bans was launched by the ALA in April 2022 to fight the surge in book bans , and now comprises more than 200 partner organizations and tens of thousands of individual supporters.

Books and looks: gen Z is ‘rediscovering’ the public library

Young people are using the hallowed institutions at higher rates than older generations. And they’re not just there to read

H enry Earls dresses up to go to the library. He’ll plan outfits after searching “dark academic” on Pinterest, taking inspiration from the internet subculture obsessed with higher education and literature. He picks out cozy knitted sweaters and accessorizes with well-worn copies of classic books. Earls looks like an adjunct English professor – or an extra in Saltburn .

“I want to cultivate an aesthetic when I go to the library,” the 20-year-old Cooper Union art student said. “And, honestly, I dress up to see if someone will come up to me and say hi.”

When Earls isn’t studying at the New York Public Library, he cruises the reading room for friends – or more than friends. Last week, he (respectfully) slipped his number to a young woman sitting near him, which led to a flirty text exchange. A few days ago, he made a friend on the library steps, a law student prepping for an exam.

“We met in an environment that supports focus and growth, so we hit it off,” Earls said. “He might come hang out with my friends and me sometime.”

Gen Z seems to love public libraries. A November report from the American Library Association (ALA) drawing from ethnographic research and a 2022 survey found that gen Z and millennials are using public libraries, both in person and digitally, at higher rates than older generations.

More than half of the survey’s 2,075 respondents had visited a physical library within the past 12 months. Not all of them were bookworms: according to the report, 43% of gen Z and millennials don’t identify as readers – but about half of those non-readers still visited their local library in the past year. Black gen Zers and millennials visit libraries at particularly high rates.

Libraries have never been just about books. These are community hubs, places to connect and discover. For an extremely online generation that’s nearly synonymous with the so-called “loneliness epidemic”, libraries are increasingly social spaces, too.

“We traditionally think of libraries as very quiet, and parts of them are, but what we observed watching gen Z in libraries is that there are some really great spaces for teens, big rooms where they can do things like gaming or making their own music,” said Rachel Noorda, a co-author of the ALA report. “It’s a place to be solitary, but also a place to build community.”

And a place to flex. On TikTok, Earls posts selfie videos showing him studying, journaling or reading in front of the Bryant Park library’s breathtaking beaux-arts backdrop. The clips get millions of views. “I think people my age are craving something more authentic, and looking for something that’s real,” Earls said. “What’s more real than books and physical material?”

Library-related content does well on #booktok, where young literary influencers – many of them still in high school – drive sales by recommending and reviewing stories. ( Colleen Hoover , #booktok’s favorite author, shot to the top of bestseller lists due to viral endorsements; other recommended books often fall into the “ romantasy ” young adult category.)

“A lot of my followers find libraries appealing in an aesthetic way,” said Marwa Medjahed, an 18-year-old TikToker who posts about life as a George Washington University freshman to her 115,000 followers. “They feel like I’m enjoying studying, rather than being in a bleak dorm room with harsh lighting.”

While many young people read digitally, downloading (or pirating) titles, hard copies of books are fetishized on social media. “Ebooks don’t make good props on TikTok,” Kathi Inman Berens, co-author of the ALA report, said. “You need book materiality, a printed book, something that helps visually.” Why buy the title when you can just borrow it at the library?

Tom Worcester, 28, is one of the co-founders of Reading Rhythms, a New York-based “reading party” held at bars. Attendees pay $20 to cozy up with their books while DJs play ambient tracks in the background. Guests can mingle in between sets. The events are held twice weekly, but that doesn’t stop Worcester from going to real libraries, too. “If I know I have a good four-hour block of time to myself, I’ll ask a bunch of friends, ‘Do you want to go to the library today?’” he said. “I make it a social event.”

At the end of last year, Worcester and a friend took a trip to Amsterdam, where they visited the Openbare Bibliotheek. Inside the second-largest library in Europe, the pair conducted personal “annual reviews”, spending hours reflecting on the highs and lows of their year. “When you’re at the library, there’s an unspoken agreement that you will focus on what you have to do,” he said.

Talk to any young and online person long enough about libraries and they’ll inevitably bring up the “third place”, a term coined in 1989 by the urban sociologist Ray Oldenburg. Like attachment styles or imposter syndrome, the third place is an academic term turned social media discourse point. Separate from home and work, it is a space for gathering and socialization. Bars, coffee shops, churches and libraries are the usual examples.

Gen Z’s well aware that they lack many of the third places their parents had, especially as the lines between work and home blurred during Covid. Libraries are the last place they feel exists that asks nothing of them. You can truly come as you are.

“Coffee shops get so crowded, and you have to spend money to be there, but libraries are open for everyone,” said Anika Neumeyer, a 19-year-old English student who volunteers at the Seattle Public Library. “There’s a lot less pressure to be doing something in the public library. No one’s going to judge you.”

In 2018, the librarian and academic Fobazi Ettarh coined the term “vocational awe”. It describes the idea that libraries are “inherently good” and “beyond critique”, which can lead to the exploitation of their workers. Abby Hargreaves, a librarian in the Washington DC area who posts about her job to 48,000 TikTok followers, believes gen Z has a tendency to romanticize the position.

“There’s this idea of ‘I’ll go to my library and have some great adventure while I’m there,’” Hargreaves said. “But then we also see people who are looking to tear libraries down, whether that’s through budget cuts or legislated book bans.”

If gen Z is going to save libraries, they couldn’t pick a better time to advocate for them: across the country, these institutions and their workers are under attack. Last year, Mayor Eric Adams of New York City slashed funding to public libraries, cutting Sunday service in the five boroughs – and drawing the ire of Cardi B , who went on an Instagram Live tirade over the news.

A series of library-related bills are making their way through Idaho’s legislature that would restrict material it deems inappropriate for minors and allow family members to file $2,500 lawsuits against libraries that violate the law. Last year, Missouri Republicans attempted to strip all state funding from public libraries. This week, Chaya Raichik, the rightwing influencer behind Libs of Tiktok, was appointed to a library advisory position for Oklahoma’s schools, which means she could help determine what books are “appropriate” for students.

Meanwhile, school librarians in states across the country report enduring harassment – and for some, death threats – by rightwing trolls just for doing their jobs.

“It’s so strange when you hear ‘Oh, gen Z loves libraries,’ or when the algorithm keeps feeding you videos of beautiful libraries, but then there’s no more Sunday service and you have to wait weeks for your book to come,” said Anna Murphy, an upper school librarian at the Berkeley Carroll School in Brooklyn. “The library love and hate seems to exist in two different universes.”

Emily Drabinski, president of the ALA, reminds us that the vast majority of US voters oppose book bans and hold librarians in “high regard”. “Most people love the library, especially after 50 years of systematic disinvestment of public institutions, since it’s the only one left standing,” she said.

Arlo Platt Zolov is a 15-year-old who lives in Brooklyn and has what must be one of the all-time-best after-school jobs: running the information desk at the central branch of the public library, steps away from Prospect Park. “A lot of people my age are surrounded by tech and everything’s moving so quickly,” he said. “Part of me thinks we’re rediscovering libraries not as something new, but for what they’ve always been: a shared space of comfort.”

Ryan Walters says voters elected him to decide which books should be in school libraries.

State schools Superintendent Ryan Walters says his election in a statewide race is a primary reason why the state Board of Education has the right to decide what books should be on the shelves of libraries in school districts with locally elected school boards.

State schools Superintendent Ryan Walters addresses the board at the February meeting of the Oklahoma state school board, Thursday, Feb. 22, 2024.

After Thursday's state board meeting Walters was asked about a lawsuit filed Tuesday by Edmond Public Schools against him, the state board and the Oklahoma State Department of Education. Edmond Superintendent Angela Grunewald said the lawsuit was filed after the OSDE threatened to lower the district’s accreditation over a dispute about books in the libraries of the district’s three high schools. The Edmond school board voted unanimously to approve the lawsuit.

In its lawsuit, the district asked the Oklahoma Supreme Court to decide whether the state board or a local, elected school board has the authority to establish policies concerning books in the district’s libraries. On Wednesday afternoon, the court set a hearing in the case before a court referee on March 5.

The district, and at least one influential state lawmaker, has cast the issue as one of local control. But Walters seemed to reject that idea when meeting with members of the media after Thursday’s meeting.

Why have a state department of education?

“We have the authority to ensure that there’s not pornography or sexually explicit material in the classroom, so we’re going to exercise that authority,” Walters said. If a district is able to do whatever it wants, he asked "why do we have a State Department of Education? Why did voters vote for me to be in this position? To go in and clean schools up."

Prep for the polls: See who is running for president and compare where they stand on key issues in our Voter Guide

Walters said, "We’re going to be asking questions." He said "ensuring that districts aren’t abusing students and parents by putting that kind of filth in front of their kids is how we’ve gotten the state back on track. I’m not going to let the state go backwards, because we have a few rogue districts that want to go out there and allow pornography in classrooms across the state.”

Local control, he said, "left us with ‘Gender Queer,’ ‘Flamer’ and all of these books in classrooms across the state. So we came into office and said this isn’t going to be allowed anymore."

Neither of those books were cited by OSDE’s general counsel, Bryan Cleveland, in his letter to the Edmond district. Cleveland’s letter said two other books, the “The Glass Castle” by Jeannette Walls and “The Kite Runner” by Khaled Hosseini had been reviewed by the agency’s Library Media Advisory Committee and deemed unfit for a school library.

The only publicly identified member of that committee is Chaya Raichik , a New York woman behind the conservative “Libs of TikTok” social media account. OSDE officials have steadfastly refused to reveal the names of other board members.

Edmond: "We do not have pornography in our libraries"

Grunewald disputed the committee’s finding on Tuesday, emphatically saying, “We do not have pornography in our classrooms and our libraries at Edmond Public Schools.”

The lawsuit also questions the legality of the process used by the state board to pass rules such as the one it adopted in March 2023, when it approved a proposal by Walters to ban “pornographic” materials from school libraries. The district argues the rules didn’t go into effect because they were disapproved by the Legislature. Gov. Kevin Stitt later approved them anyway.

Walters said the Edmond district is “challenging the entire rule and saying the State Department of Education cannot take pornography off the shelves for your kids. The voters were clear in Oklahoma, when they voted me into office, to clean up our schools and get the focus back on academics. We have done that from day one and you now have a district, Edmond Public Schools, that want to be the champion of bringing pornography back to schools, by claiming we don’t have that authority. That’s an outrageous accusation.”

Lawmaker says Edmond district should insist on local control

State Rep. Mark McBride, R-Moore, the chair of the state House of Representatives’ appropriation and budget subcommittee on education, has said the Edmond district is well within its legal right to insist on local control on such an issue.

It was McBride’s letter to Oklahoma Attorney General Gentner Drummond that led to an opinion from Drummond last April about whether or not the state Board of Education had the authority to make rules such as the one regarding pornographic material.

The opinion said while the Legislature can authorize the state board to make rules, the section law (Title 70, Section 3-104 of the Oklahoma Statutes) “does not authorize rulemaking on a specific statute or subject.” Drummond's opinion also said “(a)ny rule promulgated relying only on the general ‘powers and duties’ within (that section of law) is invalid and may not be enforced by the State Department of Education or the Board.”

Last March , Drummond also warned that state agencies can't enact administrative rules without first receiving a directive from the Oklahoma Legislature.

“It’s a local-control issue and I think the attorney general has answered that question,” McBride said Wednesday. “As a Republican, I believe in local control and not a nanny state.”

Using Q&As and examples, our in-depth guide explains the accounting for investments in debt and equity securities. ASC 320 applies to investments in debt securities, and ASC 321 applies to investments in equity securities and other ownership interests in an entity.

This February 2024 edition adds guidance on the fair value option for financial instruments and other interpretations related to investments in debt and equity securities based on frequent questions we experience in practice. 

Applicability

  • Companies that hold investments in debt and equity securities  
  • Companies that hold financial instruments in the scope of ASC 825-10

Relevant dates

  • Effective immediately

Perspectives on investment accounting and the fair value option

Investment accounting is how we refer to the accounting for debt and equity securities that don’t fall under other accounting models, such as the equity method or consolidation. These remaining investments typically give the investor limited (if any) influence over the investee.  

The first comprehensive accounting and reporting guidance on investments in debt and equity securities was issued in 1993. Nearly 30 years later, some of those requirements and concepts are still present – including the core principles for classification and accounting for debt securities. But there have been several changes (especially for equity securities) as well as challenges in applying the guidance to new facts and circumstances and new types of investments.

This updated publication also addresses the application of the fair value option. The fair value option can be elected for a wide range of financial assets and liabilities, including investments in debt and equity securities. It allows these instruments to be measured at fair value on a recurring basis.

In bringing this guidance together, we aim to help you effectively and efficiently identify the guidance that applies to different types of investments and understand the related accounting requirements. We walk you through available accounting options so that you can make the choice that is right for you.
