A couple years ago I found a great site called something like 'programming-books.com' (but not exactly that).
It let users submit links to their favorite books for various programming languages, and write a short blurb about why they're so good. You could include their Amazon page and the website would grab a cover picture.
I've since lost that bookmark and am trying to find it again, anyone know what site I'm talking about? Is it still around?
