The 1st Ed. books are still in there. You can buy them (at least, you could a week ago, because I did). However, they're not easy to find. The filters are backwards or something. I can only get to them by trying to pick them, which results in them not appearing, and if you click enough, you get booted back out into a screen that allows you to pick the OS you want to buy books for and THEN you see the 1st Ed. books available to buy.
