Books Like This

A book's details and any film or series made from it. For requests like "tell me about Project Hail Mary", "is The Name of the Wind being made into a film?", "how long is Dune?". Misspellings are fine. If screen_checked is false, the film and TV check could not run just now, so the film and TV status is unknown.

Books like one the user enjoyed, or for a genre. For requests like "books like The Martian" or "a good cosy mystery". Suggestions are English-language books for the same readers (picture book, children, young adult or adult), one per author and one per series. Well-read books of the same kind come first (picked_from: shelf, and because names the kind, for example "celebrated dystopian novels"), then books sharing specific subjects on Open Library (picked_from: subjects, and because lists the shared subjects). Novels never get self-help, textbooks, anthologies, study guides, category romance lines or explicit books as suggestions, and popular books are preferred over obscure ones. Other books by the same author are left out unless same_author=true. Give title or subject; common other titles work (1984, The Sorcerer's Stone)
