Whenever I see a collection of (e)Books, I have this urge to build something that functions the following way: You pick a topic out of the collection, the page tells you the prerequisites to understand the topic along with books covering that topic. For each book, it shows a tree of books, beginning with one that requires no prior knowledge up to a book that covers the topic. Something that shows you a "path to mastery". Do you think something like that is practical?
