Same handshake clock as this listing (overlay / warm / seed; live tools/list only if that is missing). Indigo is live_ok, amber is auth_required, gray is unreachable. Not a SAFE badge. Stdio listings have no badge.

Tools
(9)-
openlibrary_search_booksFull-text book search across Open Library works. Supports field filters (title, author, subject, publisher, ISBN, language) and returns work-level records with edition counts, cover IDs, and reading availability. Use query for general search or combine specific field filters. Results are work-level — drill into editions via openlibrary_get_editions.
-
openlibrary_get_workFetch a work by Open Library Work ID (OL…W). Returns title, description, subjects, cover IDs, and linked author IDs for follow-up lookups. Works represent the abstract book concept independent of any specific edition. Note: author names are not included — use openlibrary_get_author or openlibrary_search_books for names.
-
openlibrary_get_editionsList editions of a work — different publishers, languages, formats, and print runs. Returns ISBNs, publisher, language, page count, and edition OLIDs. Use after openlibrary_get_work or openlibrary_search_books to find a specific printing.
-
openlibrary_get_editionFetch a single edition by identifier: ISBN-10, ISBN-13, OCLC, LCCN, or Open Library Edition ID (OL…M). Returns full edition metadata including authors, publisher, language, all identifier types, and the parent work ID. Use for ISBN lookups — pass id_type "isbn" for both ISBN-10 and ISBN-13.
-
openlibrary_search_authorsSearch Open Library authors by name. Returns Open Library Author IDs, names, birth/death dates, top works, and subject associations. Use author IDs for openlibrary_get_author (bio, remote IDs) or openlibrary_get_author_works (list of works).
-
openlibrary_get_authorFetch author detail by Open Library Author ID (OL…A). Returns bio, birth/death dates, photo IDs, and linked identifiers from Wikidata, VIAF, ISNI, Goodreads, and LibraryThing. Use openlibrary_search_authors to find an author ID first.
-
openlibrary_get_author_worksList works by an author. Returns titles, cover IDs, and work OLIDs for drilling into editions or details. Use openlibrary_get_author for author bio and details, or openlibrary_get_editions to explore specific printings.
-
openlibrary_get_subjectBrowse works by subject. Returns matching works with edition counts and cover IDs, plus the total work count for the subject. Subjects are user-contributed and may be inconsistent ("science fiction", "Science fiction", "SF" are separate tags). Try lowercase forms first.
-
openlibrary_get_cover_urlResolve a cover image URL for a book or author photo. Returns a direct HTTPS URL in the requested size (S/M/L). The Covers API always returns HTTP 200 — missing covers return a 1×1 placeholder GIF, not a 404. URLs can be embedded in markdown as .
