Not to mention: while public libraries are great and I love them, thy are often lacking in-depth knowledge. My local public library doesn't have a book on advanced logic design, for example. It favors a more 'general' collection, and thus books with heavy reliance on math tend to be omitted. Same with in-depth law books, they just aren't there.
