What AI Cannot Do Here

Large language models like ChatGPT, Claude, and Gemini regularly hallucinate book details: wrong ISBNs, wrong publishers, wrong page counts, and even books that do not exist. The ISBN database is the only authoritative source for what was actually printed, when, and by whom. This tool queries the live Open Library catalog in real time - no guessing, no fabrication, no login.
