General information
Record identifiers such as ISBN or OCLC are sent to book cover providers, which return an image that is displayed in the Primo search results. Most covers come from one of two providers. You can right-click on an image and Inspect Element to see the source of the image.
Google Book Search
- Multiple identifiers are tested: OCLC, ISBN, LCCN, in that order.

Journals via Browzine
For any journals that are supported by Browzine, we use the cover images from Browzine, which are based on an ISSN match.
Custom covers
Record that are part of Scanned Key Content have book covers chosen by staff. These take precedence over covers provided by other sources.
