Please note that most e-books for Kindle have DRM and that doesn't allow you to share your book (or give it to someone when you no longer need it). So it's better to buy the printed version.

Amazon has a few books available without DRM-restrictions but they choose to be vague about it to keep their customers unaware.

So just that you know what Amazon has in store for you. Keep this in mind when shopping.

Also make sure you make a backup copy of your e-book. The Kindle has a back door that allows Amazon to delete a book if they wish to do so and they already have done this.

So please don't buy any books from Amazon that have DRM, just buy the printed version for your own freedom. (our grandparents died in wars for our freedom, so that's the least you can do to respect them) And if you buy any of these books then it's nice if you buy them via these links and support this site a bit. Even better is when you buy these books from a small local book store instead.
