Reserve IDs in MARC records

For some time, a lot of our partners have been requesting an easy way to pull the OverDrive Reserve ID from MARC records without having to strip it out of the URL in the 856 field. To that end, we worked with eBilboFile and OCLC to get the Reserve ID added to the 037 field for OverDrive titles. We've also added it to our own MARC Express records.

These changes took effect near the end of April, and we've published a new developer portal page to explain a little bit more about how records from each supplier work and show you an example.
