Hi and welcome.

> Hi, I am a Wikimedian who is trying to add authority control IDs on Wikidata for notable authors and titles. is there any documentation for looking up LCCNs and/or OCLC IDs for a long list of book titles? Similarly, I also want to search for individuals author/translator/editors' LCNAFs. Library of Congress has an API endpoint such as below, as documented at [APIs for LoC.gov | Library of Congress](https://www.loc.gov/apis/).

OpenRefine has a general interface to what it calls "reconciliation services" for doing this type of work. You can find a note about LCNAF reconciliation services here:

Hope that helps!
