Users should be aware that public library and academic library collections are dissimilar.
The ARL academic library study takes its definition of volume from the National Information Standards Organization (NISO): A single physical unit of any printed, typewritten, handwritten, mimeographed, or processed work, distinguished from other units by a separate binding, encasement, portfolio, or other clear distinction, which has been cataloged, classified, and made ready for use, and which is typically the unit used to charge circulation transactions.
The PLDS public library report defines "holdings" on its questionnaire: For the purpose of this data service, holdings will be defined as the number of cataloged items (number of items, NOT number of titles) plus paperbacks and videocassettes even if uncataloged.
