I just posted a whole bunch of Cornberstones of Freedom books.  They are in excellent condition--tight bindings, no water damage, not written in or highlighted, and they all meet PBS posting criteria. I am happy to offer a deal on them. If you're interested please PM me. It seems like a sin to have them just sitting here when I'm sure there are swappers who would appreciate them, and if a deal can make that happen then I'm happy to do it.
