The Problem of Too Many Books

OK, so there is a bit of a problem with having thousands of books in the house. I mentioned in an earlier post that I was re-reading the Dresden Files books. Well, I hit a bit of a roadblock. I can't find my copy of Turncoat, the eleventh book in the series. I'm still looking but this is really, really annoying. Then there's the other minor inconvenience of occasionally buying a duplicate of a book you just haven't seen on the shelves for a few years.
