Rearranging the bookshelf

Today I'm working from home. After a morning of these emails and difficult questions and issues I decided to take a 10 minutes break to ponder about some issues while rearranging my bookshelf.

Wow, it appears it is a mess. Books are randomly dumped, stacked and dropped all over the place...

This is a start. I arranged my Stephen Fry collection. By doing this I realized that I have to buy more books. I mean, why don't I have Coupland's Microserfs and Generation X?! And why is my Pratchett collection far from complete? Why do I have Nineteen eighty-four, but no Animal Farm? Etc...

This rearrangement is going to cost me a lot of money :)
