Link to a single record
Using the URL provided in the address bar of a specific catalog record page is the best way to link back to an individual record.
If the bibliographic record number is known, this URL format can be used to access that record:
https://find.library.upenn.edu/catalog/9959180943503681
To create a search that pulls in multiple individual records use the mssid: field followed by the bibliographic id number, which is provided in the direct link. Combine ids with OR:
mmsid:9940973723503681 OR mmsid:9959180943503681
Link to a search
Search queries, as they appear in the browser URL line after the completion of a search, are stable URLs that can used to regenerate a search.
