I love old book and frequent used book stores. I have a reprint of The Blaeu Atlas of Scotland, 1654, 224pgs. Up in Santa Rosa some years ago, I picked up a book for my wife (who loves the presidents); The Man Who Killed Lincoln, Philip Van Doren Stern, 1939: Random House. It includes a map of the trail that John Wilks Booth took leading to a farm house... I found a 1939 American printing of Mein Kampf: the first American printing of it: $60 bucks. I have several more old books and enjoy collecting them.
