ILLINET, established in 1975, is a statewide library alliance, representing over 3,000 academic, public, school and special libraries that are members of Illinois' library systems (RAILS, IHLS and CPLS). With the support of the Illinois State Library and the library systems, ILLINET libraries collectively provide a strong foundation for statewide resource sharing to meet the diverse information needs of Illinois citizens.
The online consortial catalogs, known as Local Library System Automation Programs (LLSAPs) and the Illinois statewide Library delivery service (ILDS) funded by the Illinois State Library through grants to IHLS, RAILS and ILDS, which is managed by CARLI are key components of statewide resource sharing. LLSAPs contain the holdings of ILLINET library collections, and provide access to circulation and interlibrary loan services. Online access to library collections, coupled with statewide delivery ensures a strong network of resource discovery and fulfillment throughout Illinois.
They also maintain the ILLINET ILL Code, which governs interlibrary loan policy within ILLINET.
The Illinois State Library collects and analyzes resource sharing and reciprocal borrowing data via the ILLINET ILL Traffic Survey. Local libraries can also view their own ILL statistics online. Completion of the ILLINET ILL Traffic Survey is required of all ILLINET member libraries in accordance with administrative rule [23 Ill. Adm. Code 3030.200 (a)(2)(O)].
