Update internal logic to allow selection of the identifiers (e.g. ISBN, UPC, etc) that Discover sends to Syndetics Unbound for cover images
The Nov 5, 2025 Discover Release Notes (https://iii.rightanswers.com/portal/app/portlets/results/viewsolution.jsp?solutionid=250108121147587&guest=0#mcetoc_1j9d37oot2) introduced format level cover images. Now only one identifier is sent to Syndetics in the following hierarchy / order:
- Configured custom 856 Cover URLs
- ISBN
- EAN/IAN
- ISSN
- UPC
This purportedly fixed an error where incorrect cover images would appear when both ISBN and UPC identifiers were sent to Syndetics, since these ISBN / UPC numbers in the cover image link might come from different records in the rollup.
However, in the case of rollups of thousands of our AV records (Music CDs and DVDs/Blu-rays), this change introduced a new issue: sending Syndetics only one identifier (ISBN) does not return a cover image at all and we're left with a generic stand-in, whereas previously sending them the UPC rather than the ISBN (or sending them both) returned the correct cover image.
Allowing iii customers to select the standard identifiers/numbers sent to Syndetics for cover image links — particularly for AV materials, since both valid ISBN and UPC numbers are often available for these records — would allow us to address this problem for rollups records where it has become an issue.
