I uploaded PDF scans of a little booklet published by Gregg in 1935, "A Pictorial Story of Shorthand" to the "Documents" section of this group. The files are all named "Story", with indication of "cover", "back cover" and then 2-page spreads. These are big files, so I probably won't leave them here long--what is our space limit with MSN groups?
Dr. Gregg loved the history of shorthand, and there are a number of articles in The Gregg Writer that discuss various historical aspects.
I have a lot of these old publications, and will try to share some of the interesting ones when I have a chance to do some scanning.
