I just mailed off a bunch of guidepost mysteries to 22 pbs members.  OVER 70 books went out.   The problem with these books is

1. they dont get posted much

2. they are pricey and hard to find

3.  there are several isbns made for each book, so posting to PBS is tricky

So I am inviting all the folks to got books from me to check in here, so you can trade titles after you have read them if you want to pass them on.  I realize some of them are keepers.
