SRU (Search/Retrieve via URL) for item records
Currently, SRU can be used to retrieve Alma bibliographic and holdings record data. In the documentation below, there are "bibliographic options" and "holdings options".
Our institution needs data from Alma on the item record level. Use case: we'd like to use SRU to count the number of items with the same item call number.
Currently if we use the "marcxml" record schema, the <numberOfRecords> returns the total number of bibliographic records. The "isohold" schema returns the number of holdings records.
Neither schema returns the total number of item records with the same item number (especially in situations where 2 or more item records are linked to the same holdings record and/or same bib record) because both schemas are counting records at the bib or holdings level.
Thank you.
