CLEVNET

CLEVNET is a library consortium headquartered at Cleveland Public Library. It was founded in 1982 and includes over 40 public library systems in northeast Ohio. CLEVNET provides access to more than 12 million titles of books, movies, music and e-books. CLEVNET was also the headquarters for Ohio's virtual reference service, KnowItNow24x7, from 2001 to its closing in 2015.

History
The origins of CLEVNET date to the automation of Cleveland Public Library's card catalog in the late 1970s and early 1980s under Director Ervin Gaines in partnership with Data Research Associates (DRA). In an effort to share the capabilities of the online catalog with other libraries, Director Gaines invited other area libraries to connect to the new technology. The Cleveland Heights - University Heights Libraries were the first library system to express interest. In December 1981, an agreement between the two library systems was approved, and the Cleveland Heights - University Heights Libraries came online on December 1, 1982, officially launching the CLEVNET consortium.

The original online catalog system ran from its inception in 1979 until a brief "shutdown" in 1990 for upgrades. The scope of the upgrade was outlined with additional details by a Letter To The Editor from Robert T. Carterette: "Clevnet is one of the largest library resource-sharing networks in the United States today, making 1.6 million titles available to public libraries throughout Northern Ohio... in addition to 4.2 million items owned by the Clevnet libraries, 1.6 million title records, 106,000 book order records, and 32,500 Union List of Periodical records must be processed, a total of 5.9 million. The system processes the 3.6 gigabytes of data."

In 2003, Cleveland Public Library, which administered CLEVNET, chose Sirsi as its new source for public library technology products and services.

In 2009, CLEVNET member libraries, including Cleveland Public Library, were the first public libraries to offer e-books to download in the EPUB format.

In 2016, CLEVNET made the decision to move its servers from Cleveland Public Library to the State of Ohio Computer Center (SOCC) in Columbus, Ohio.

In May 2017, Rocky River Public Library joined CLEVNET. In September 2018, Morley Library joined the consortium.

CLEVNET is mentioned on page 105 in the 2017 fiction work The Unclaimed Victim by D. M. Pulley, a Cleveland author.
