OCLC

OCLC, Inc. is a US-based nonprofit cooperative organization "that provides shared technology services, original research, and community programs for its membership and the library community at large". It was founded in 1967¹ as the Ohio College Library Center, then became the Online Computer Library Center as it expanded. In 2017, the name was formally changed to OCLC, Inc. OCLC and thousands of its member libraries cooperatively produce and maintain WorldCat, the largest online public access catalog in the world. OCLC is funded mainly by the fees that libraries pay (around $217.8 million annually in total ) for the many different services it offers. OCLC also maintains the Dewey Decimal Classification system.

Services

OCLC provides bibliographic, abstract and full-text information to anyone. OCLC and its member libraries cooperatively produce and maintain WorldCat—the OCLC Online Union Catalog, the largest online public access catalog (OPAC) in the world. WorldCat has holding records from public and private libraries worldwide. The Online Computer Library Center acquired the trademark and copyrights associated with the Dewey Decimal Classification System when it bought Forest Press in 1988. A browser for books with their Dewey Decimal Classifications was available until July 2013; it was replaced by the Classify Service. Until August 2009, when it was sold to Backstage Library Works, OCLC owned a preservation microfilm and digitization operation called the OCLC Preservation Service Center, with its principal office in Bethlehem, Pennsylvania. Starting in 1971, OCLC produced catalog cards for members alongside its shared online catalog; the company printed its last catalog cards on October 1, 2015. , an around-the-clock reference service provided to users by a cooperative of participating global libraries, was acquired by Springshare from OCLC in 2019 and migrated to Springshare's LibAnswers platform.

Software

OCLC commercially sells software, such as: CONTENTdm for managing digital collections Wise, an integrated library system and "community engagement system" WorldCat Discovery, a bibliographic discovery system that allows library patrons to use a single search interface to access an institution's catalog, ebooks, database subscriptions and more WorldShare Management Services, an electronic resource management system cloudLibrary, a cloud-based software system through which libraries manage and lend electronic books, digital magazines, newspapers, comics, and streaming media Meridian, a "web application and set of APIs" designed to support library resource management workflows involving linked data. Meridian is part of OCLC's larger linked data strategy.

Research

OCLC has been conducting research for the library community for more than 30 years. In accordance with its mission, OCLC makes its research outcomes known through various publications. These publications, including journal articles, reports, newsletters, and presentations, are available through the organization's website. OCLC Publications – Research articles from various journals including The Code4Lib Journal, OCLC Research, Reference and User Services Quarterly, College & Research Libraries News, Art Libraries Journal, and National Education Association Newsletter. The most recent publications are displayed first, and all archived resources, starting in 1970¹, are also available. Membership Reports – A number of significant reports on topics ranging from virtual reference in libraries to perceptions about library funding. Newsletters – Current and archived newsletters for the library and archive community. Presentations – Presentations from both guest speakers and OCLC research from conferences, webcasts, and other events. The presentations are organized into five categories: Conference presentations, Dewey presentations, Distinguished Seminar Series, Guest presentations, and Research staff presentations. During the COVID-19 pandemic, OCLC participated in the REopening Archives, Libraries, and Museums (REALM) project funded by the IMLS to study the surface transmission risks of SARS-CoV-2 on common library and museum materials and surfaces, and published a series of reports.

Advocacy

Advocacy has been a part of OCLC's mission since its founding in 1967. OCLC staff members meet and work regularly with library leaders, information professionals, researchers, entrepreneurs, political leaders, trustees, students and patrons to advocate "advancing research, scholarship, education, community development, information access, and global cooperation". WebJunction, which provides training services to librarians, is a division of OCLC funded by grants from the Bill & Melinda Gates Foundation beginning in 2003. OCLC partnered with search engine providers in 2003 to advocate for libraries and share information across the Internet landscape. Google, Yahoo!, and Ask.com all collaborated with OCLC to make WorldCat records searchable through those search engines. OCLC's advocacy campaign "Geek the Library", started in 2009, highlights the role of public libraries. The campaign, funded by a grant from the Bill & Melinda Gates Foundation, uses a strategy based on the findings of the 2008 OCLC report, "From Awareness to Funding: A study of library support in America". Other past advocacy campaigns have focused on sharing the knowledge gained from library and information research. Such projects have included communities such as the Society of American Archivists, the Open Archives Initiative, the Institute for Museum and Library Services, the International Organization for Standardization, the National Information Standards Organization, the World Wide Web Consortium, the Internet Engineering Task Force, and Internet2. One of the most successful contributions to this effort was the Dublin Core Metadata Initiative, "an open forum of libraries, archives, museums, technology organizations, and software companies who work together to develop interoperable online metadata standards that support a broad range of purposes and business models." OCLC has collaborated with the Wikimedia Foundation and the Wikimedia volunteer community, through integrating library metadata with Wikimedia projects, hosting a Wikipedian in residence, and doing a national training program through WebJunction called "Wikipedia + Libraries: Better Together".

Online database: WorldCat

OCLC's WorldCat database is used by the general public and by librarians for cataloging and research. WorldCat is available to the public for searching via a subscription web-based service called FirstSearch, to which many libraries subscribe, as well as through the publicly available WorldCat.org.

Identifiers and linked data

OCLC assigns a unique accession number referred to as an "OCN", an "OCLC Control Number" or an "OCLC number" to each new bibliographic record in WorldCat. This is somewhat analogous to how the Library of Congress assigns an "LCCN" or a "Library of Congress Control Number" to its bibliographic records (but LCCNs can be prefixed and are thus extended to other uses too like authority control, etc.). Numbers are assigned serially, and in mid-2013 over a billion OCNs had been created. In September 2013, OCLC declared these numbers to be in the public domain, removing a perceived barrier to widespread use of OCNs outside OCLC itself. The control numbers link WorldCat's records to local library system records by providing a common reference key for a record in libraries. OCNs are particularly useful as identifiers for books and other bibliographic materials that do not have ISBNs (e.g., books published before 1970). OCNs are often used as identifiers for Wikipedia and Wikidata. In October 2013, it was reported that out of 29,673 instances of book infoboxes in Wikipedia, "there were 23,304 ISBNs and 15,226 OCNs", and regarding Wikidata: "of around 14 million Wikidata items, 28,741 were books. 5,403 Wikidata items have an ISBN associated with them and 12,262 have OCNs." OCLC also runs the Virtual International Authority File (VIAF), an international name authority file, with oversight from the VIAF Council composed of representatives of institutions that contribute data to VIAF. VIAF numbers are broadly used as standard identifiers, including in Wikipedia. In 2024, OCLC launched a new linked data management tool called OCLC Meridian. This was released with a suite of APIs for WorldCat Entities to allow greater control, connection and integration of linked data for user institutions. This suite of APIs "enables the creation of linked data entities and descriptive relationships, forming connections to the existing value in MARC records and other datasets across the global information ecosystem". The use of these APIs and WorldCat Entities is designed to "improve discoverability and relevance for users", "integrate data management into your existing workflows" and "discover, emphasize and analyze important relationships". A set of WorldCat Entities APIs "enables users to connect identifiers from disparate sources (such as ORCID, ISNI, VIAF, etc.), learn of changes to WorldCat Entities data" and related information for local use.

Company acquisitions

(the Netherlands)]] OCLC acquired NetLibrary, a provider of electronic books and textbooks, in 2002 and sold it in 2010 to EBSCO Industries. OCLC owns 100% of the shares of OCLC PICA, a library automation systems and services company which has its headquarters in Leiden in the Netherlands and which was renamed "OCLC" at the end of 2007. In July 2006, the Research Libraries Group (RLG) merged with OCLC. On January 11, 2008, OCLC announced that it had purchased EZproxy. It has also acquired OAIster. The process started in January 2009 and from October 31, 2009, OAIster records are freely available via WorldCat.org. In 2013, OCLC acquired the Dutch library automation company HKA and its integrated library system Wise, which OCLC calls a "community engagement system" that "combines the power of customer relationship management, marketing, and analytics with ILS functions". OCLC began offering Wise to libraries in the United States in 2019. In January 2015, OCLC acquired Sustainable Collection Services (SCS). SCS offered consulting services based on analyzing library print collection data to help libraries manage and share materials. In 2017, OCLC acquired Relais International, a library interlibrary loan service provider based in Ottawa, Canada. A more complete list of mergers and acquisitions is available on the OCLC website.

Criticism

In May 2008, OCLC was criticized by Jeffrey Beall for monopolistic practices, among other faults. Library blogger Rick Mason responded that although he thought Beall had some "valid criticisms" of OCLC, he demurred from some of Beall's statements and warned readers to "beware the hyperbole and the personal nature of his criticism, for they strongly overshadow that which is worth stating". In November 2008, the Board of Directors of OCLC unilaterally issued a new Policy for Use and Transfer of WorldCat Records that would have required member libraries to include an OCLC policy note on their bibliographic records; the policy caused an uproar among librarian bloggers. Among those who protested the policy was the non-librarian activist Aaron Swartz, who believed the policy would threaten projects such as the Open Library, Zotero, and Wikipedia, and who started a petition to "Stop the OCLC powergrab". Swartz's petition garnered 858 signatures, but the details of his proposed actions went largely unheeded. Within a few months, the library community had forced OCLC to retract its policy and to create a Review Board to consult with member libraries more transparently. In August 2012, OCLC recommended that member libraries adopt the Open Data Commons Attribution (ODC-BY) license when sharing library catalog data, although some member libraries have explicit agreements with OCLC that they can publish catalog data using the CC0 Public Domain Dedication. In 2025, OCLC dropped the lawsuit it brought in 2024 in Ohio against a librarian and employee of the University of California, Berkeley Libraries who denied involvement in Anna's Archive's large-scale web scraping of WorldCat after the judge had deferred a number of issues to the Ohio Supreme Court due to the unprecedented nature of the case (see ). Technology writer Glyn Moody criticized the suit as "costly and pointless", saying it went against OCLC's stated mission of making information accessible.
