accession number - A unique number assigned to each bibliographic item in the order in which it is added to a library collection, and recorded in an accession record maintained in the technical services department. In most libraries, accession numbers are assigned in continuous numerical sequence, but some libraries use a code system designed to indicate type of material and/or year of accession, as well as accession order. ;
