I have at least that many books, except many of my shelves are two deep. Most are rescues from garage sales. I hate to see a good book thrown away.
My wife refuses to go "garage saleing" with me anymore because I always buy several books.
On those rarer than rare occasions that we actually do go to a garage sale, she adminishes "No books! Gottit?" before we get out of the car.
It never works.
