Each result carries `best_edition` — one edition of the work, with its `isbn_13`/`isbn_10` where Open Library has them, and its `edition_key`, which can be passed to `get_book_by_id` as `{ idType: "olid" }` for that edition's full record.get_book_by_titleSearch for a book by its title on Open Library.
