I-Share Institution Identifiers

How to interpret the information on this page:

Library = I-Share institution. Click the institution name to get to the library’s full entry in the CARLI database
3-letter Code = your institution’s three-letter code assigned by CARLI
Item barcode prefix = the prefix(es) in active use by the library in their item records.
Conversion item barcode prefix = the “fake” barcode number assigned to item records in the conversion from LCS to DRA. Not applicable to many I-Share libraries.
Current patron barcode format = the prefix (if applicable) plus number of digits in active use in patron records for the library
Alternate patron barcode prefix = a prefix reserved for the library’s patron records, but not necessarily in active use
Alma Institution Code = your institution’s Alma Institution Code, assigned by Ex Libris.
Ex Libris 4-digit Code = your institution’s numeric customer code, assigned by Ex Libris. This number can be used to identify other I-Share institutions’ involvement in the request process in Alma or as the source of bibliographic records in Primo VE.

NOTE: to search for a specific prefix (item or patron), use your browser’s Find functionality (often control+F).
