Like I told Allison earlier his month, if you have the space and the leisure to set the books out in a row on the floor (I used the floor tiles and made an alphabet grid) and put them all there first before putting them back on the shelves you may be surprised at the repeats. I was able to do some serious weeding that way and probably got a couple hundred bucks from Half-Price Books for things I already had or will never read again.
