Cleaned my bookcases!

I went through my books and cleaned out the bookcases. I didn't take photos of all of the three bookcases that I went through. I took before and after photos of one bookcase. I am going to get another bookcase of similar size to the one below. The  books I am not keeping (there are about 23 grocery bags full) are going to be donated to my church, used book store, and to a charity betterworldbooks.com. Has anyone gone through there own collection of books lately? Previously, it had been more than three years for me to go through all of mine.
