Books and Media (https://find.library.duke.edu)
URLs for bibliographic details pages in Books & Media will have different formats depending on whether the bibliographic record was created in Aleph and migrated to Alma, or whether it was created directly in Alma.
We’ll refer to records created in Aleph and migrated to Alma as “Aleph-born”, and records created in Alma directly (after cutover on July 10th) as “Alma-born.”
Bibliographic record identifiers in Aleph
When an bib record was created in Aleph, it received a nine-digit Aleph sysid that served as the unique record identifier.
The Aleph sysid was used to create the URL in Books & Media.
For example, if an Aleph-born record was in Books & Media with the URL https://find.library.duke.edu/catalog/DUKE002109345, the last nine digits - 002109345 - are the Aleph sysID.
Migrating an Aleph-born record to Alma
In Alma, the unique record identifier for the bibliographic record is called the MMS ID.
When an Aleph-born record is migrated to Alma, the Aleph sysid is used to build the new Alma MMS ID.
The format of an Alma MMS ID for an Aleph-born record is
99 + Aleph-born sysid + 010 + 8501
99 indicates that this identifier is for a bibliographic record
010 is an identifier added to the record by the Ex Libris Aleph-to-Alma migration scripts
8501 is Duke’s Ex Libris institutional id
Example:
A bibliographic record was created in Aleph and assigned a sysid of 002109345
When that record migrated to Alma, it was assigned an Alma MMDID of 990021093450108501
Bibliographic record identifiers for Alma-born records
An Alma-born bibliographic record is assigned an MMS ID when it is created.
The format of an Alma MMS ID for an Alma-born record is
99 + unique record identifier + 8501
99 indicates that this identifier is for a bibliographic record
The unique record identifier is a 10 digit numeric string
8501 is Duke’s Ex Libris institutional ID
