Oh, I know what I’m doing today when I catch some free time! I’m camping out at Freebook Sifter.
Freebook Sifter is a compilation site of, you guessed it, free ebooks. It has the books sifted into categories and subcategories, including breaking the Children’s eBooks category into age groups and other relevant subjects.
Another advantage is users have rated the ebooks as well. Be aware though that not all books listed are for young eyes!
