PICA only provides holdings to its own users in the Pica3 communication protocol at the moment. Pica plans to provide location and holdings information to Z39.50 users at the beginning of next year. University of Calif provides holdings using the OPAC record syntax in the holdingsAndCircData fields. 2.3 Z39.50 Clients Z39.50 client systems must also accommodate holdings in the record display. Indications are that vendors are not taking a consistent approach and that not all clients presently available in the market will display holdings, although several vendors have indicated that their next version will accommodate holdings.
Location indicates the stack location within the library.
Each copy is listed separately. When there are multiple branches within a system each bibliographic record is listed separately. This type of display works well for individual library systems but may not be suitable within a union catalogue with many locations to display. For serials the holdings display is more problematic than monographs. The databases searched do not appear to show which issues the library holds.
