I went by Book Buyers (large used book store about a block away) today to see what they'd want from my surplus books. I had by far the largest single batch of books there, with five boxes full. The check-in guy asked me what I had, and I opened one of them to show a box full of paperbacks. He said, "Oh" in a happy way.
They took most of the books, leaving me with one box at the end of the day, and $150 in store credit.
Both as a matter of curiosity and in case anyone is interested in taking some of them, here are the books they did not want (many of which I haven't read):
Bad Habits (Dave Barry)
The Call Of The Wild (Jack London)
Computer: Those Amazing Machines (a National Geographic Book, a touch dated as it's from 1985)
Criminal Evidence For Police, 2nd Edition (Paul B. Weston, Kenneth M. Wells)
Cycle Of The Werewolf (Stephen King)
Deathbeast (David Gerrold)
