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/).
"[https://www.id.loc.gov/search/?all=True&fo=json&q=Book+Title&st=list](https://www.id.loc.gov/search/?all=True&fo=json&q=Book+Title&st=list)"

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!

Thanks much for your quick response. What I cannot find is what's mentioned in № 5: “Copy the JSON -- that's the entire contents of the text file (PersonalNamesReconcile.txt for personal names only; CorporateNamesReconcile.txt for corporate names only; GenericNamesReconcile.txt for a mix of both personal and corporate names\*\*) -- in its entirety and paste into the pop-up window. Click "Perform Operations".”

Hi Subhashish,
You may also be interested in these reconciliation services for LC vocabularies:
[https://github.com/cmharlow/lc-reconcile](https://github.com/cmharlow/lc-reconcile)
[https://refine.codefork.com/](https://refine.codefork.com/)
I would note that the latter service sometimes has incorrect labels, perhaps since it searches VIAF rather than performing a direct search of LC--sometimes there is a lag between when a heading is updated in LC and when the change appears in VIAF.
Best,
