OCLC began in 1967, as the
Ohio College Library Center, through a
Ohio university presidents, vice presidents, and
library directors who wanted to create a cooperative, computerized
Ohio libraries. The group first met on July 5, 1967 on the
campus of the
Ohio State University to sign the articles of
incorporation for the nonprofit organization. The group hired
Frederick G. Kilgour , a former
Yale University medical school
librarian, to design the shared cataloging system. Kilgour wished to
merge the latest information storage and retrieval system of the time,
the computer, with the oldest, the library. The plan was to merge the
Ohio libraries electronically through a computer network
and database in order to streamline operations, control costs, and
increase efficiency in library management. The goal of this network
and database was to bring libraries together to cooperatively keep
track of the world's information in order to best serve researchers
and scholars. The first library to do online cataloging through OCLC
Alden Library at
Ohio University on August 26, 1971. This was
the first occurrence of online cataloging by any library worldwide.
OCLC is based on use of services and contribution of
data. Between 1967 and 1977,
OCLC membership was limited to
institutions in Ohio, but in 1978, a new governance structure was
established that allowed institutions from other states to join. In
2002, the governance structure was again modified to accommodate
participation from outside the United States.
OCLC expanded services in the
United States outside of Ohio, it
relied on establishing strategic partnerships with "networks,"
organizations that provided training, support and marketing services.
By 2008, there were 15 independent
United States regional service
OCLC networks played a key role in
OCLC governance, with
networks electing delegates to serve on
OCLC Members Council. During
OCLC commissioned two studies to look at distribution channels;
at the same time, the
OCLC Members Council approved governance changes
that had been recommended by the Board of Trustees which severed the
tie between the networks and governance. In early 2009, OCLC
negotiated new contracts with the former networks and opened a
centralized support center.
OCLC provides bibliographic , abstract and full-text information to
OCLC and its member libraries cooperatively produce and maintain
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 Open
launched in late 2003, exposed a subset of
WorldCat records to Web
users via popular Internet search, bibliographic, and bookselling
WorldCat later morphed into WorldCat.org. In October
OCLC technical staff began a wiki project, WikiD, allowing
readers to add commentary and structured-field information associated
WorldCat record. WikiD was later phased out.
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 , U.S.
The reference management service QuestionPoint provides libraries
with tools to communicate with users. This around-the-clock reference
service is provided by a cooperative of participating global

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 its predecessor,
OCLC Passport, was phased out in
WorldCat contains records in MAchine Readable Cataloging (MARC )
format contributed by library catalogers worldwide who use
OCLC as a
cataloging tool, and these MARC format records can also be downloaded
into other libraries' local catalog systems. This allows libraries to
find and download records for materials they are adding to their local
catalog, without having to undergo the lengthy process of creating a
new catalog entry from scratch for each new item.
As of March 2015, the
OCLC database contained over 336 million
records with 2.2 billion cataloged items, and is the world's largest
bibliographic database covering 72,000 libraries. Connexion is
available to professional librarians as a computer program or on the
web at connexion.oclc.org.
WorldCat is available to the public for searching via a subscription
web-based service called FirstSearch, as well as through the publicly
IDENTIFIERS AND LINKED DATA
OCLC assigns a unique control number (referred to as an "OCN" for
OCLC Control Number") to each new bibliographic record in the
WorldCat. Numbers are assigned serially, and as of mid-2013 over a
billion OCNs had been created. In September 2013, the
these numbers to be in the public domain , removing a perceived
barrier to widespread use of OCNs outside of
OCLC itself. The control
numbers link WorldCat's records to local library system records by
providing a common reference key for a record across 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 used as identifiers often in and
Wikidata . In October 2013, it was reported that out of 29,673
Infobox Book in, "there were 23,304 ISBNs and
15,226 OCNs"; and regarding Wikidata: "of around 14 million Wikidata
items, 28,741 were books. 5403
Wikidata items have an
with them, and 12,262 have OCNs."
OCLC also runs the Virtual International Authority
File (VIAF), an
international name authority file. VIAF numbers are broadly used as
