"The Statewide Illinois Library Catalog, known as SILC, is Illinois' first all inclusive statewide union catalog that integrates WorldCat and the Illinois Library Systems' local consortial OPACs, to provide both shelf status and interlibrary loan capabilities in a single searchable interface. SILC resides on the familiar FirstSearch platform as an additional WorldCat database that allows users to scope to regional groups within Illinois, as well as by type of library. From a single WorldCat record, users will be able to link to a local shared catalog record to see if and where an item is available for loan."
