In the past, we have covered some of the sites you can visit to find free books to download to your Kindle or other e-reader devices. Amazon has plenty of free books too. Keeping up with them all to find great titles to download should not be time consuming. Freebook Sifter is a very simple tool that provides you with a list of free books you can get on Amazon.com.
The idea here is very simple: the tool allows you to search through free books by category. Ratings and average star for each title are made available. You can filter books by language and get daily new book alerts by email. An RSS feed for new books is available also.
Freebook Sifter may not have a fancy user-interface but it does help you find free books to consume on your Kindle device. The idea has potential.
