Improve Visibility of Services Available from CDI – Match with Multiple ISBNs / EISBNs

August 2021
Previously, only the first ISBN and EISBN were used to retrieve electronic services available from CDI. With this enhancement, Primo VE will include additional ISBNs and EISBNs (up to five each) to the OpenURL request using the new parameters rft.isbn_list and rft.eisbn_list, and the Alma link resolver will now store these values in the CTO and use them to match active, available portfolios (see Alma August 2021 Release Notes).

Notes from the August Alma Release: “Alma Link Resolver now supports incoming CDI OpenURLs with multiple ISBNs and eISBNs.  Alma will use these ISBNs and eISBNs to match bibliographic records and return all relevant electronic services.”

Notes from August Primo Release Notes: “Previously, only the first ISBN and EISBN were used to retrieve electronic services available from CDI. With this enhancement, Primo will include additional ISBNs and EISBNs (up to five each) to the OpenURL request using the new parameters rft.isbn_list and rft.eisbn_list, and the Alma/SFX link resolver will store these values in the CTO and use them to match active, available portfolios.
