Open Library
Books, authors and covers from the Internet Archive.
Open Library exposes bibliographic data for tens of millions of books — search, works, editions, covers — maintained by the Internet Archive. Great for reading apps and coursework. Bulk users should download the data dumps instead of crawling the API.
