Selecting preferred sources for importing records
Is it possible to choose which sources (library catalogues, databases etc.) are preferred for pulling metadata? I've got a large number of ISBNs to import into a group library, and it would be useful to this project to choose sources with richer records (especially formatted contents from MARC 505).
ISBN import also doesn't have all that many catalogs to choose from.
ISBN import is only supported from
LoC, K10+, BnF, and Open Worldcat with 2-3 additional catalogs restricted by ISBN and in that order.
If you want to prefer, say, BnF over LoC, while not possible via GUI, that's a trivial code change. Adding additional catalogs with ISBN import is a significant coding effort.
