Si nous vivions en 1913 / Antoine Prost. (OCLC #878360972)
Did you know that if you update an existing OCLC record by putting a new call number in an 090, that call number won’t be saved in the master record? They do get saved in new records (maybe in records with no other call number?), so I’d been assuming they’d save. For the existing record for this title, I added a complete call number in an 050.
Before I assign a new call number, I always peek into nearby OPACs using OCLC’s “Find in a Library” service; sometimes I find a good call number that may have unintentionally not been shared.
