I have known that Amazon puts different books online for free at the Kindle Store, and the books listed changes all the time. It might not change all of them every day, but at least some of them change each day. But, here is what I didn't know until this morning. Amazon also has a list of the top 100 free books that you can look through. You can also narrow the selection down by choosing the catagory that you want to see book about. As an example, mystery fiction, or maybe non-fiction like cook books or healthy living. Whatever catagory you choose, you still get to see the top 100 free books in that catagory. This is an awesome way to get free books, not only for casual reading enjoyment; but also to learn about things that interest you. These are not just books you are borrowing, they actually become part of your Kindle library, and can be lended to your friends. You do not have to have an actual Kindle to use this feature, so any computer or tablet or phone that you can have the Kindle Reading app on will work for this .
