ILLINOIS STATE LIBRARY
Illinois Regional Library Systems
Illinois Library Systems work with the Illinois State Library to serve their communities to create a multitype network of cooperative library resource sharing accessible to all Illinois residents. The key functions of the Library Systems include the administration of online consortial catalogs, known as Local Library System Automation Programs (LLSAPs) and the Illinois Statewide Library Delivery Service (ILDS).
Library systems were established by the Illinois Library System Act (75 ILCS 10/). Support for the Illinois Library Systems is provided through the Secretary of State's office with funds appropriated by the Illinois General Assembly.
