I have a large collection of books. Most of it falls into a category I refer to as "Mind Candy". It is tasty, but not very filling. Most of it is fantasy and sci-fi genre, some is popular fiction, and some is heady philosophical stuff. I love the fact that one wall of my study is invisible; covered by three floor to ceiling bookcases and stuffed with books.
One special category in my library is made up of the the wonderful treasures I find in used book stores. I really like old books, especially books on philosphy, theology and music. I am building quite a collection of old hymnals and music theory books. One of them is such a gem, I've been spending some of my free time transcribing it to HTML. It's called "The Organist and the Choirmaster" and was written in 1952 by a church musician named Charles L. Etherington.
I'm planning on getting my whole library up here at some point, but until that time, feel free to take a peek at my childhood comic book collection.
