ThingISBN, our popular ISBN-based API, supports and returns data for two more identifiers: LCCN and OCLC.
If you feed it an LCCN or an OCLC number you don’t need to add “&allids=1″ to get back these identifiers.
- I haven’t added LCCNs and OCLC numbers to the ThingISBN feed, yet.
- Although there are some details to be worked out, this advance looks forward to adding support for LCCNs and OCLC numbers to LibraryThing for Libraries.
Caveat. ThingISBN is free for non-commercial use. Commercial use requires our say-so. Read more here.
In the news! Coincidentally, LCCNs are in the news this week. Yesterday, the Library of Congress announced a “LCCN Permalink,” a smart bid to convert a vital but underused set of permanent, unique IDs, the LCCN (Library of Congress Control Number), into the regnant permanent, unqiue ID, the URL. See Catalogablog for the announcement.
