Summary
The right source for bibliographic facts, because a model's memory of ISBNs and publication years is unreliable.
Asked about a book, a model will produce a plausible edition, year and author that are subtly wrong — and there is no way to tell from the answer. Open Library is an actual catalogue, openly licensed and free to query, so the check costs nothing. Worth connecting for anything where a citation has to be right rather than approximately right.
