Libraries in Clackamas County (LINCC) is a consortium of the public libraries of Clackamas County, Oregon. It was established in 1977 when the first county-wide funding levy was approved by county voters. LINCC is a resource and revenue sharing network with a single library computer system. The consortium remains distinct from the Library District of Clackamas County created by a ballot measure voted on during the 2008 general election.

Consortium

LINCC includes: The Happy Valley Library was originally opened as the Sunnyside branch of the Clackamas County Library in 2012 to replace the Clackamas Corner branch near the Clackamas Town Center. The county transferred the library to the City of Happy Valley effective July 1, 2015. The City of Gladstone transferred their local library to Clackamas County effective December 1, 2019. The member libraries share an integrated library system which allows cooperative borrowing. Shared services, including cataloging, computer support, courier, and interlibrary loan, are coordinated by the Network Office, a department of the county government. The system currently offers nearly half a million titles, 1.2 million items, and serves over 200,000 members, who check out more than 6.2 million items each year.

Library District

In November 2008, Measure 3-310 was passed by Clackamas County voters, leading to the creation of a Library District that established permanent property tax-based funding for libraries in the county. The cities of Damascus, Tualatin, and Johnson City opted out of the district's creation. In May 2010, a close vote by the small subset of Tualatin residents who are also Clackamas County residents meant that they would join the district. Following a petition signed by 300 Damascus residents, Damascus voters approved a measure to join the Clackamas County library district in November 2010.
