DPP Store offers eBooks and has a nice selection of free children’s books under the category: Kid’s eBooks.  Look for the year published as Out of Copyright and you will have found the classic kid’s lit.  Books in this category include some of my favorites like books by Frances H. Burnett that I read time and again as a child, Heidi by Johanna Spyri, Rebecca of Sunnybrook Farm by Kate Douglas Wiggin, Wind in the Willows by Kenneth Grahame, and the list goes on.  This is a great place to find classic books to load on computers or reading devices for kids to take on trips.  Even better, how about reading aloud in the car some of the books that touched you as a child, just the titles of these take me right back to reading on a blanket out in the tall grass behind our house.  Me and the grasshoppers and a great book separate from the larger world.
