A bibliographic item can be any information entity (e.g., books, computer files, graphics, realia, cartographic materials, etc) that is considered library material (e.g., a single novel in an anthology), or a group of library materials (e.g., a trilogy), or linked from the catalog (e.g., a webpage) as far as it is relevant to the catalog and to the users (patrons) of the library.
