Literature in Gregg

Hi, Everybody!
I really enjoy this group and the wealth of knowledge it has about shorthand, so maybe someone can answer this.
Reading Gregg-written literature is a favorite way that I keep up my speed and also meet the challenge of reading older Gregg (pre-Anniversary). I have a few titles in my modest collection, but I was wondering:  Does anyone have, or know, where I can find a full listing of the "literature" books that were published by Gregg (excluding the Gregg Writer magazines)??  .
