Our Library ConsortiumBookheart

The McHenry Public Library District is a member of a consortium of nearly 30 libraries in the Chicago area. This consortium, called CCS (Cooperative Computer Services), allows each library to enjoy the benefit of a much larger online catalog of materials for patrons to search and borrow from or place holds, a shared patron database, discounted group licenses to other sources of data, the associated hardware and software, the expertise of the CCS staff, and the opportunity to network with the other member libraries.

This cooperative structure has proven to be more efficient and cost-effective than libraries operating independently (like those in the list below). To see the list of all of the libraries in the CCS consortium, click here.
