I-Share Common Definitions for Local Extensions

In Alma's consortial environment, bibliographic records are shared between the Network Zone (NZ) and each library's Institution Zone (IZ). The shared bibliographic record should contain descriptive metadata and authorized access points that apply to all copies of the work described. Individual I-Share libraries may add local description pertaining to their copies using designated local extensions, which are bibliographic MARC tags that are assigned to store and display metadata at the institution level. Libraries may also choose to record local data in holding records.

Ex Libris allows libraries to designate tags in the following ranges as local extensions: 09X, 59X, 69X, 77X, 78X, and 950-999. CARLI will be establishing some of these tags with consortial definitions for consistency in application, indexing, and reporting. Other tags will be left to libraries for their own needs. Information is available on CARLI's How-To: Local Extensions for Copy-Specific Bibliographic Data.

The following table identifies the tags and their current definitions. As I-Share libraries become more comfortable with Alma, CARLI may establish additional fields as local extensions with a common consortial definition.

Neither Ex Libris nor OCLC requires that we continue to use any local extensions in the same manner as identified by Bibliographic Formats and Standards. OCLC allows libraries to use 9XX fields for any local needs in their own databases. CARLI does not guarantee that 9XX fields will be retained in shared NZ records. 

Alma bibliographic metadata may be mapped into other fields for export or publishing to different services.
