@older @inventaire @tivasyk Wow, I hadn't known of #inventaire! Thanks for mentioning that!
From a quick look, it doesn't have fields for LCC (Library of Congress Classification), publication date, etc. I did a test import of a book: https://www.librarything.com/work/25717416/details/268620860 vs https://inventaire.io/entity/isbn:9780937175101 . LT pulled publication date, LCC, Dewey, publisher, and correct cover from its databases and the Library of Congress. Inventaire got the wrong cover, has no LCC or Dewey, and doesn't support tags. 1/
