  • add_to_libraryLog reading on the signed-in reader's Siftivo shelves: add a book to want to read (NOT_STARTED), mark it READING, FINISHED or DNF, rate it, or record progress.No findings

    Description, as the server wrote it
    Log reading on the signed-in reader's Siftivo shelves: add a book to want to read (NOT_STARTED), mark it READING, FINISHED or DNF, rate it, or record progress. Suits "add X to my list", "I just finished X, four stars" and "I'm halfway through X". "Finished it, four and a half stars" is one call with readingStatus FINISHED and rating 4.5. The workId comes from search_books. Each field given replaces what the reader had there before, so send a rating or a note only when they asked for that one to change. Omitting readingStatus leaves the book on the shelf it is already on. Needs a linked Siftivo account.

    Description, as the server wrote it
    Take a book off the signed-in reader's shelves entirely, discarding its shelf, progress and notes. The reader's rating for the book stays.

    Why it is in this group

    Description, as the server wrote it
    Book recommendations from a mood, theme or subject in the reader's own words: "cozy fantasy with found family", "a good book about grief", "something light for the beach". Matches on meaning rather than on a title or an author name. For a reader who has linked their Siftivo account, the results leave out books already in their library and books they hid, avoided or recently passed on, and a result that fits their taste says why.

    Description, as the server wrote it
    Book recommendations from books the reader already loved, named by title: "books like Project Hail Mary", "I loved Circe and Piranesi, what else would I like", a book club that enjoyed one pick. Titles are resolved against the catalog first, and any that do not resolve are reported back rather than guessed at. Other books by the same authors are left out. For a reader who has linked their Siftivo account, the results leave out books already in their library and books they hid, avoided or recently passed on, and a result that fits their taste says why.

    Description, as the server wrote it

    • The name "get_my_taste" says "get": a word for reading.
    Description, as the server wrote it
    The signed-in reader's taste: the books, authors, series, genres and moods they love, what they avoid or quit, why each one counts, and how far from their usual taste they like to range. A recommendation for this reader rests on it, so it suits "what should I read next", "recommend me a book", "something I would like" and "what kind of books do I like" when no book or mood is named. The strongest 40 entries come back by default, and limit raises that. Needs a linked Siftivo account. It is the same profile the app's own recommendations use.

Suits "what should I read after X", "is there a sequel to X" and "more like X".
