About

Stacks puts open book and archive catalogues behind one connector. Open Library: search 40 million records by words, title, author, subject, language or year, with ratings, edition counts, covers, ISBNs and ebook availability; works in full with description, subjects and rating distribution; editions by ISBN with publisher, date, pages and identifiers; authors with dates, bio, links and top works; subject pages with top works, authors and related subjects; trending titles. Project Gutenberg: the 78,000-title public-domain catalogue bundled and searched locally, download links in every format, and the text itself — chapter list, any passage, or every occurrence of a phrase. LibriVox: free audiobooks with runtime and links. Internet Archive: search texts, audio, film, software and images by words, collection, creator and year; item metadata and files; the Wayback Machine's closest snapshot of any URL. Keyless; nothing stored.
