Pay what you want. All together, these ebooks would cost over $680. But at Humble Bundle, you choose the price and increase your contribution to upgrade your bundle! This bundle has a minimum $1 purchase.

Read them anywhere. These books are available in PDF, ePUB, and MOBI formats, meaning you can read them anywhere at any time. Instructions and a list of recommended reading programs can be found online.
