Cannot remember where I found the link, probably from the Panda Newsletter that I'm subscribed to, but here is a website focused on recommendations for good books to read. What separates this site from others is that the book recommendations on this site come from “successful people.” Whether that matters to you or not, there are some pretty good books listed on the site. You can sort by categories, or by people, or you can view their Top 100 list of good books to read. Seems like a good site to bookmark.
