Internet Archive Downloader

Internet Archive (archive.org) holds more than 34 millions books. Some books are permitted to read online by borrowing for a limit period. With the extension, the borrowed books can be downloaded for offline reading.
HathiTrust Digital Library (hathitrust.org) is also supported. All books with full view permission can be downloaded.
