The Library Consortium of Eastern Idaho (LCEI) is a consortium of multi-type libraries serving the public of Eastern Idaho. It encourages collaboration, resource sharing, staff development and technical innovations among its member libraries to ensure that the citizens of Eastern Idaho receive quality, up-to-date library services and have access to current, accurate information. The consortium was formerly known as Eastern Idaho Library Network (EILNet). In early 2003 the 20 libraries of EILnet merged with several other libraries, known as Eastern Idaho Libraries (EILS), to form the new consortium.
The consortium has grown in membership from 8 small public libraries to its current membership of 24 libraries including district libraries, public libraries, school/community libraries and a college library. Member libraries serve over 230,000 Idahoans in 11 Idaho counties. The counties served are: Bannock, Bear Lake, Bingham, Bonneville, Caribou, Custer, Franklin, Fremont, Jefferson, Lemhi, Madison, and Teton.
