I have been contacted by a historical researcher from Mercer County and he informed me of documents at Marietta College in Marietta, Ohio. The documents are from the John Mathews collection. John Mathews operated a store near the fort and receipts and other papers from his business are at Marietta.
After several starts and stops a paperback version of the book is now available. I will have a few copies by early next week. It is for sale at $35 at Amazon.com. (Less when they have a sale) Long story short, that is about what we have to charge to show a profit. We will also have books at the museum and Silver Cross as well. Those books we may be able to sell a little cheaper. All books will be paperback.
