Feedbooks is a universal e-paper web-site compatible with all e-paper devices where you can download thousands of free e-books, publish and share your own content, and create customized newspapers from RSS feeds and widgets.
Feedbooks developed its own technology to generate e-books on the fly. Using both semantic and presentation elements, Feedbooks can generate high-quality e-books in any format. Instead of using terminal formats, Feedbooks strictly work with an abstract representation of the content, and therefore it can easily be extended and adapt itself to new formats.
Formats currently supported:
- ePub application/epub+zip
- Mobipocket/Kindle application/x-mobipocket-ebook
- PDF application/pdf
- Sony Reader
- Custom PDF
Users can also upload their own books. These will then be available in any of the above formats.
Feedbooks also supports OPDS for feeds and access to books. They used to have RSS access to the site contents but this has been discontinued.
