ETA: Most of my AG books were ruined when the pipes burst in the basement on Christmas Eve, 2009. I was really sad because I thought they were fine (in a plastic bin) but the bin had holes, and my AG books took most of the water. I guess I should be glad that the pictures and whatnot were fine, since the books are replaceable, but I'm still really sad about it.
Oh well - I'm sure I can pick them up on Amazon for pretty cheap.
