Internet Archive Downloader

Internet Archive 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 is also supported. All books with full view permission can be downloaded.

The extension works by fetching every leaf of a book, constructing a PDF stream on the fly targeting to disk storage. So it consumes only a little RAM resource and can handle books of thousands of leafs easily.
