The request "Cherished Book" with "what to use" is ambiguous: it does not name a product or a platform, so the best fit depends on whether the user wants to find, track, or look up a book. For searching and tracking books, SansFiction 8 and Casey Hand's Project Gutenberg tools 2 fit most directly, and Google Cloud Books 3 offers a book search API.
A question back: Do you want to find a specific book, track the books you have read, or get details such as copies or editions for a book you already own?
