It looks like those IA items lack a MARC record, but have an XML metadata record? For example: https://ia800703.us.archive.org/32/items/worksstephenoli00churgoog/worksstephenoli00churgoog_meta.xml If the OCLC number is reliably present maybe it would be possible to use it to look up a record using the OCLC Metadata API? https://www.oclc.org/developer/api/oclc-apis/worldcat-metadata-api.en.html There might be a way to batch download in MarcEdit, or the process could (in theory) be scripted fairly easily using their REST API? https://developer.api.oclc.org/wc-metadata#/Bibliographic%20Records/read-bib I think it would be worth letting IA know about the situation using the email address in that Google Doc. It seems like this is a situation they would be interested in resolving since their instructions seem to be lacking. Good luck! //Ed
