A library catalog (or library catalogue in British English) is a register of all bibliographic items found in a library or group of libraries, such as a network of libraries at several locations. A catalog for a group of libraries is also called a union catalog. A bibliographic item can be any information entity (e.g., books, computer files, graphics, realia, cartographic materials, etc.) that is considered library material (e.g., a single novel in an anthology), or a group of library materials (e.g., a trilogy), or linked from the catalog (e.g., a webpage) as far as it is relevant to the catalog and to the users (patrons) of the library.
The card catalog was a familiar sight to library users for generations, but it has been effectively replaced by the online public access catalog (OPAC). Some still refer to the online catalog as a "card catalog". [2] Some libraries with OPAC access still have card catalogs on site, but these are now strictly a secondary resource and are seldom updated. Many libraries that retain their physical card catalog will post a sign advising the last year that the card catalog was updated. Some libraries have eliminated their card catalog in favor of the OPAC for the purpose of saving space for other use, such as additional shelving.
The largest international library catalog in the world is the WorldCat union catalog managed by the non-profit library cooperative OCLC. [3] In January 2021, WorldCat had over half a billion catalog records and three billion library holdings. [4]
Antonio Genesio Maria Panizzi in 1841 [5] and Charles Ammi Cutter in 1876 [6] undertook pioneering work in the definition of early cataloging rule sets formulated according to theoretical models. Cutter made an explicit statement regarding the objectives of a bibliographic system in his Rules for a Printed Dictionary Catalog. [7] According to Cutter, those objectives were
1. to enable a person to find a book of which any of the following is known (Identifying objective):
2. to show what the library has (Collocating objective)
3. to assist in the choice of a book (Evaluating objective)
These objectives can still be recognized in more modern definitions [8] formulated throughout the 20th century.
Other influential pioneers in this area were Shiyali Ramamrita Ranganathan and Seymour Lubetzky. [9]
Cutter's objectives were revised by Lubetzky and the Conference on Cataloging Principles (CCP) in Paris in 1960/1961, resulting in the Paris Principles (PP).
A more recent attempt to describe a library catalog's functions was made in 1998 with Functional Requirements for Bibliographic Records (FRBR), which defines four user tasks: find, identify, select, and obtain. [10]
A catalog helps to serve as an inventory or bookkeeping of the library's contents. If an item is not found in the catalog, the user may continue their search at another library.
A catalog card is an individual entry in a library catalog containing bibliographic information, including the author's name, title, and location. Eventually the mechanization of the modern era brought the efficiencies of card catalogs. It was around 1780 that the first card catalog appeared in Vienna. It solved the problems of the structural catalogs in marble and clay from ancient times and the later codex—handwritten and bound—catalogs that were manifestly inflexible and presented high costs in editing to reflect a changing collection. [11] The first cards may have been French playing cards, which in the 1700s were blank on one side. [12]
In November 1789, during the dechristianization of France during the French Revolution, the process of collecting all books from religious houses was initiated. Using these books in a new system of public libraries included an inventory of all books. The backs of the playing cards contained the bibliographic information for each book and this inventory became known as the "French Cataloging Code of 1791". [13]
English inventor Francis Ronalds began using a catalog of cards to manage his growing book collection around 1815, which has been denoted as the first practical use of the system. [14] [15] In the mid-1800s, Natale Battezzati, an Italian publisher, developed a card system for booksellers in which cards represented authors, titles and subjects. Very shortly afterward, Melvil Dewey and other American librarians began to champion the card catalog because of its great expandability. In some libraries books were cataloged based on the size of the book while other libraries organized based only on the author's name. [16] This made finding a book difficult.
The first issue of Library Journal , the official publication of the American Library Association (ALA), made clear that the most pressing issues facing libraries were the lack of a standardized catalog and an agency to administer a centralized catalog. Responding to the standardization matter, the ALA formed a committee that quickly recommended the 2-by-5-inch (5 cm × 13 cm) "Harvard College-size" cards as used at Harvard and the Boston Athenaeum. It also suggested that a larger card, approximately 3 by 5 inches (8 cm × 13 cm), would be preferable. By the end of the nineteenth century, the bigger card won out, mainly to the fact that the 3-by-5-inch (8 cm × 13 cm) card was already the "postal size" used for postcards.
Melvil Dewey saw well beyond the importance of standardized cards and sought to outfit virtually all facets of library operations. To the end he established a Supplies Department as part of the ALA, later to become a stand-alone company renamed the Library Bureau. In one of its early distribution catalogs, the bureau pointed out that "no other business had been organized with the definite purpose of supplying libraries". With a focus on machine-cut index cards and the trays and cabinets to contain them, the Library Bureau became a veritable furniture store, selling tables, chairs, shelves and display cases, as well as date stamps, newspaper holders, hole punchers, paper weights, and virtually anything else a library could possibly need. With this one-stop shopping service, Dewey left an enduring mark on libraries across the country. Uniformity spread from library to library. [17]
Dewey and others devised a system where books were organized by subject, then alphabetized based on the author's name. Each book was assigned a call number which identified the subject and location, with a decimal point dividing different sections of the call number. The call number on the card matched a number written on the spine of each book. [16] In 1860, Ezra Abbot began designing a card catalog that was easily accessible and secure for keeping the cards in order; he managed this by placing the cards on edge between two wooden blocks. He published his findings in the annual report of the library for 1863 and they were adopted by many American libraries. [13]
Work on the catalog began in 1862 and within the first year, 35,762 catalog cards had been created. Catalog cards were 2 by 5 inches (5 cm × 13 cm); the Harvard College size. One of the first acts of the newly formed American Library Association in 1908 was to set standards for the size of the cards used in American libraries, thus making their manufacture and the manufacture of cabinets, uniform. [12] OCLC, major supplier of catalog cards, printed the last one in October 2015. [18]
In a physical catalog, the information about each item is on a separate card, which is placed in order in the catalog drawer depending on the type of record. If it was a non-fiction record, Charles A. Cutter's classification system would help the patron find the book they wanted in a quick fashion. Cutter's classification system is as follows: [19]
Traditionally, there are the following types of catalog:
The earliest librarians created rules for how to record the details of the catalog. By 700 BCE the Assyrians followed the rules set down by the Babylonians. The seventh century BCE Babylonian Library of Ashurbanipal was led by the librarian Ibnissaru who prescribed a catalog of clay tablets by subject. Subject catalogs were the rule of the day, and author catalogs were unknown at that time. The frequent use of subject-only catalogs hints that there was a code of practice among early catalog librarians and that they followed some set of rules for subject assignment and the recording of the details of each item. These rules created efficiency through consistency—the catalog librarian knew how to record each item without reinventing the rules each time, and the reader knew what to expect with each visit. The task of recording the contents of libraries is more than an instinct or a compulsive tic exercised by librarians; it began as a way to broadcast to readers what is available among the stacks of materials. The tradition of open stacks of printed books is paradigmatic to modern American library users, but ancient libraries featured stacks of clay or prepaper scrolls that resisted browsing.[ citation needed ]
As librarian, Gottfried van Swieten introduced the world's first card catalog (1780) as the Prefect of the Imperial Library, Austria. [11]
During the early modern period, libraries were organized through the direction of the librarian in charge. There was no universal method, so some books were organized by language or book material, for example, but most scholarly libraries had recognizable categories (like philosophy, saints, mathematics). The first library to list titles alphabetically under each subject was the Sorbonne library in Paris. Library catalogs originated as manuscript lists, arranged by format (folio, quarto, etc.) or in a rough alphabetical arrangement by author. Before printing, librarians had to enter new acquisitions into the margins of the catalog list until a new one was created. Because of the nature of creating texts at this time, most catalogs were not able to keep up with new acquisitions. [21]
When the printing press became well-established, strict cataloging became necessary because of the influx of printed materials. Printed catalogs, sometimes called dictionary catalogs, began to be published in the early modern period and enabled scholars outside a library to gain an idea of its contents. [22] Copies of these in the library itself would sometimes be interleaved with blank leaves on which additions could be recorded, or bound as guardbooks in which slips of paper were bound in for new entries. Slips could also be kept loose in cardboard or tin boxes, stored on shelves. The first card catalogs appeared in the late 19th century after the standardization of the 5 in. x 3 in. card for personal filing systems, enabling much more flexibility, and toward the end of the 20th century the online public access catalog was developed (see below). These gradually became more common as some libraries progressively abandoned such other catalog formats as paper slips (either loose or in sheaf catalog form), and guardbooks. The beginning of the Library of Congress's catalog card service in 1911 led to the use of these cards in the majority of American libraries. An equivalent scheme in the United Kingdom was operated by the British National Bibliography from 1956 [23] and was subscribed to by many public and other libraries.
More about the early history of library catalogs has been collected in 1956 by Strout. [34]
In a title catalog, one can distinguish two sort orders:
The grammatical sort order has the advantage that often, the most important word of the title is also a good keyword (question 3), and it is the word most users remember first when their memory is incomplete. To its disadvantage, many elaborate grammatical rules are needed, so many users may only search with help from a librarian.
In some catalogs, persons' names are standardized (i. e., the name of the person is always cataloged and sorted in a standard form) even if it appears differently in the library material. This standardization is achieved by a process called authority control. Simply put, authority control is defined as the establishment and maintenance of consistent forms of terms – such as names, subjects, and titles – to be used as headings in bibliographic records. [35] An advantage of the authority control is that it is easier to answer question 2 (Which works of some author does the library have?). On the other hand, it may be more difficult to answer question 1 (Does the library have some specific material?) if the material spells the author in a peculiar variant. For the cataloger, it may incur too much work to check whether Smith, J. is Smith, John or Smith, Jack.
For some works, even the title can be standardized. The technical term for this is uniform title . For example, translations and re-editions are sometimes sorted under their original title. In many catalogs, parts of the Bible are sorted under the standard name of the book(s) they contain. The plays of William Shakespeare are another frequently cited example of the role played by a uniform title in the library catalog.
Many complications about alphabetic sorting of entries arise. Some examples:
In a subject catalog, one has to decide on which classification system to use. The cataloger will select appropriate subject headings for the bibliographic item and a unique classification number (sometimes known as a "call number") which is used not only for identification but also for the purposes of shelving, placing items with similar subjects near one another, which aids in browsing by library users, who are thus often able to take advantage of serendipity in their search process.
Online cataloging, through such systems as the Dynix software [36] developed in 1983 and used widely through the late 1990s, [37] has greatly enhanced the usability of catalogs, thanks to the rise of MARC standards (an acronym for MAchine Readable Cataloging) in the 1960s. [38]
Rules governing the creation of MARC catalog records include not only formal cataloging rules such as Anglo-American Cataloguing Rules, second edition (AACR2), [39] Resource Description and Access (RDA) [40] but also rules specific to MARC, available from both the U.S. Library of Congress and from OCLC, which builds and maintains WorldCat. [41]
MARC was originally used to automate the creation of physical catalog cards, but its use evolved into direct access to the MARC computer files during the search process. [42]
OPACs have enhanced usability over traditional card formats because: [43]
The Cutter Expansive Classification system is a library classification system devised by Charles Ammi Cutter. The system was the basis for the top categories of the Library of Congress Classification.
The Dewey Decimal Classification (DDC), colloquially known as the Dewey Decimal System, is a proprietary library classification system which allows new books to be added to a library in their appropriate location based on subject. It was first published in the United States by Melvil Dewey in 1876. Originally described in a 44-page pamphlet, it has been expanded to multiple volumes and revised through 23 major editions, the latest printed in 2011. It is also available in an abridged version suitable for smaller libraries. OCLC, a non-profit cooperative that serves libraries, currently maintains the system and licenses online access to WebDewey, a continuously updated version for catalogers.
The reference desk or information desk of a library is a public service counter where professional librarians provide library users with direction to library materials, advice on library collections and services, and expertise on multiple kinds of information from multiple sources.
Seymour Lubetzky was a major cataloging theorist and a prominent librarian.

A discovery system is a bibliographic search system based on search engine technology. It is part of the concept of Library 2.0 and is intended to supplement or even replace the existing OPAC catalogs. These systems emerged in the late 2000s in response to user desire for a more convenient search option similar to that of internet search engine. The results from searching a discovery system may include books and other print materials from the library's catalog, electronic resources such as e-journals or videos, and items stored in other libraries.
Charles Ammi Cutter was an American librarian. In the 1850s and 1860s he assisted with the re-cataloging of the Harvard College library, producing America's first public card catalog. The card system proved more flexible for librarians and far more useful to patrons than the old method of entering titles in chronological order in large books. In 1868 he joined the Boston Athenaeum, making its card catalog an international model. Cutter promoted centralized cataloging of books, which became the standard practice at the Library of Congress. He was elected to leadership positions in numerous library organizations at the local and national level. Cutter is remembered for the Cutter Expansive Classification, his system of giving standardized classification numbers to each book, and arranging them on shelves by that number so that books on similar topics would be shelved together.
Landsbókasafn Íslands – Háskólabókasafn is the national library of Iceland which also functions as the university library of the University of Iceland. The library was established on December 1, 1994, in Reykjavík, Iceland, with the merger of the former national library, Landsbókasafn Íslands, and the university library. It is the largest library in Iceland with about one million items in various collections. The library's largest collection is the national collection containing almost all written works published in Iceland and items related to Iceland published elsewhere. The library is the main legal deposit library in Iceland. The library also has a large manuscript collection with mostly early modern and modern manuscripts, and a collection of published Icelandic music and other audio. The library houses the largest academic collection in Iceland, most of which can be borrowed for off-site use by holders of library cards. University students get library cards for free, but anyone can acquire a card for a small fee. The library is open for public access.
An index card consists of card stock cut to a standard size, used for recording and storing small amounts of discrete data. A collection of such cards either serves as, or aids the creation of, an index for expedited lookup of information. This system is said to have been invented by Carl Linnaeus, around 1760.
An integrated library system (ILS), also known as a library management system (LMS), is an enterprise resource planning system for a library, used to track items owned, orders made, bills paid, and patrons who have borrowed.
In library and information science, cataloging (US) or cataloguing (UK) is the process of creating metadata representing information resources, such as books, sound recordings, moving images, etc. Cataloging provides information such as author's names, titles, and subject terms that describe resources, typically through the creation of bibliographic records. The records serve as surrogates for the stored information resources. Since the 1970s these metadata are in machine-readable form and are indexed by information retrieval tools, such as bibliographic databases or search engines. While typically the cataloging process results in the production of library catalogs, it also produces other types of discovery tools for documents and collections.
The so-called Preußische Instruktionen or PI are a cataloging set of rules for libraries which was used in scientific libraries in German-speaking countries and beyond. First published in 1899, the PI were replaced by other sets of rules such as the Regeln für die alphabetische Katalogisierung (RAK) from the 1980s onwards, which in turn have been replaced by the Resource Description and Access (RDA) rules since 2015.
A bibliographic database is a database of bibliographic records. This is an organised online collection of references to published written works like journal and newspaper articles, conference proceedings, reports, government and legal publications, patents and books. In contrast to library catalogue entries, a majority of the records in bibliographic databases describe articles and conference papers rather than complete monographs, and they generally contain very rich subject descriptions in the form of keywords, subject classification terms, or abstracts.
Frederick Gridley Kilgour was an American librarian and educator known as the founding director of OCLC, an international computer library network and database. He was its president and executive director from 1967 to 1980.
Charles Coffin Jewett was an American librarian, in 1848 becoming the Librarian and Assistant Secretary of the Smithsonian Institution before being appointed superintendent of the Boston Public Library in 1858. He was born in Lebanon, Maine.
Knowledge organization (KO), organization of knowledge, organization of information, or information organization is an intellectual discipline concerned with activities such as document description, indexing, and classification that serve to provide systems of representation and order for knowledge and information objects. According to The Organization of Information by Joudrey and Taylor, information organization:
examines the activities carried out and tools used by people who work in places that accumulate information resources for the use of humankind, both immediately and for posterity. It discusses the processes that are in place to make resources findable, whether someone is searching for a single known item or is browsing through hundreds of resources just hoping to discover something useful. Information organization supports a myriad of information-seeking scenarios.
A bibliographic index is a bibliography intended to help find a publication. Citations are usually listed by author and subject in separate sections, or in a single alphabetical sequence under a system of authorized headings collectively known as controlled vocabulary, developed over time by the indexing service. Indexes of this kind are issued in print periodical form, online, or both. Since the 1970s, they are typically generated as output from bibliographic databases.
Library history is a subdiscipline within library science and library and information science focusing on the history of libraries and their role in societies and cultures. Some see the field as a subset of information history. Library history is an academic discipline and should not be confused with its object of study : the discipline is much younger than the libraries it studies. Library history begins in ancient societies through contemporary issues facing libraries today. Topics include recording mediums, cataloguing systems, scholars, scribes, library supporters and librarians.
James Christian Meinich Hanson was a Norwegian born, American librarian.
The Paris Principles (PP), also known as the Statement of Principles, defined the theoretical foundation for the creation of bibliographical cataloging rules for libraries. They were specified and agreed upon in October 1961 at the Conference on Cataloguing Principles (CCP) of the International Federation of Library Associations and Institutions (IFLA) in Paris.
