Speaking of old books, I have a neat, but not too valuable find coming my way- a grouping of four antique children's school books, the earliest of which is pre-Civil War, dating to the 1850's. The owner of the books tried unsucessfully to sell them on Ebay and could not interest a book seller in them. The condition apparently isn't that great. She posted them for free on Craigslist, saying she wanted them to go to someone who would truly be interested in having them. She said that she simply couldn't stand to just throw them out.
As it happens, I'm writing a novel, and I'm right at a part that is set in a rural Victorian schoolhouse where the books are old hand-me-downs, and a child's primer is going to play an important role in the scene. So I will be able to write one of these books directly into the story. It always helps to have the real thing to work from like this! In exchange for her gift of the books, I'll be sending her a copy of my book when it is done. So it kind of a neat trade!
