Deb-IN reference to your question, I believe I have the only copy of this book. It is written by three different Gleasons. If you look in the introduction of John Barber White's book, you will see he mentions Daniel A. Gleason papers as being unpublished. But eventually Elon Gleason took over the research, after his death William Gleason of Delhi, NY added a small portion to the back, and then had all three sections leather bound. All the pages are typewriter written. I purchased the book in a used book shop in western NY. I hope to reformat the book and overlay Barber's book into it, first because i always wanted to write a book, and secondly, i would like to get this info out there, if something terrible happens to my house, the info would be lost forever. The book isn't indexed, so look ups are a challenge, but i'm more than willing to help out where i can.
