How does WorldCat Collection Analysis work?
Using your library’s holding symbol (an identifier indicating that your library owns an item), the service takes call numbers in your WorldCat records and maps them to the OCLC Conspectus [Microsoft Excel]. The OCLC Conspectus structure is a hierarchical classification scheme that allows libraries to analyze their entire collections by subject instead of call number. Since the service supports multiple classification schemes, individual libraries can get a more complete picture of their collections, and members of groups can more easily compare their collections.
