An online public access catalog (often abbreviated as OPAC or simply library catalog) is an online database of materials held by a library or group of libraries. Users search in library catalog principally to locate books and other material available at a library. In simple language it is an electronic version of the card catalog. OPAC is the gateway to library's collection.
