I have an unpostable copy. It is in great shape, ISBN 0395137195. Spine is strong, no water damage or anything. The unpostable part is that it has yellow highlighted sections on some pages. It really doesn't interfere with reading (to me anyway) and would still work very well for a homeschool classroom or school assignment reading. Order any 2 books from my shelf and I will send it as a freebie (first to PM me and requewst 2 books gets it) I will remove this post when it is gone.

Thanks:)
