My local library has an inter library program that you can request books from other libraries if it's not in stock at mine. Give them a dollar and they track down a book for you to rent and then once you're done, it goes back to the original library.
Asked for a copy of Unrepentant Sinner by Col. Charles Askins. Several days later, it was ready for pickup. Took it home and opened it up to start reading, and found a very surprising note written in front.
The only person that comes to mind is Rudy Etchen that passed away in 2001.
Imagine my surprise to find a signed and dedicated copy.
