Not aimed at only you, but a trend in posts like these: When it's no particular order and you don't comment on what a book is or why you recommend it, I feel the list becomes kinda useless. And when a post is upvoted much that contains a lot of elements, I don't know which book gained those votes.

One value of an unordered unannotated book list is in reinforcing books you've already read, and providing a little extra push towards the action potential on the ones you haven't.
