My place has many hundreds (or thousands) more books than I'd like. My wife is a problem. Since these books are doing nothing but gathering dust, I'd say culling them would be a great idea. Keep the stuff that is either valuable (either cash or sentiment) or special (large format and art books, for example). Otherwise, I'd like to get rid of a couple of thousand books. If you'd like some to leave at your vacation home, let me know.
