I have published the transcribed Civil War letters from William A. Harding to his brother (and my great-great-great grandfather) Palmer Harding. The book is available on Amazon; the paperback
edition for $5 at www.amazon.com/dp/1481915045 and the Kindle edition for $1.50 at www.amazon.com/dp/B013HBLI68. I have blogged about these letters, and transcribing them has been a work in progress for years. I am happy to finally have them out there for others to read!
