{Sketch: Digital typography history, extended} {Dave Walden} {In 2017 I had the opportunity to be an observer at a meeting at the Computer History Museum (\acro{CHM}) of pioneers in desktop publishing and the technologies leading to desktop publishing. That resulted in me being involved with two special desktop-publishing (\acro{DTP}) issues the \textit{\acro{IEEE} Annals of the History of Computing}. The meeting and helping with the journal issues made me aware of several less well known aspects of evolution of \acro{DTP} technology and the \acro{DTP} business, including the roles of the Rocappi company, the Seybold Reports and Seminars, the Atex business and its newspaper and periodical publishing systems, and more. In addition to sketching some of these (or other) activities in my presentation, I will also give pointers into the evolving literature and archives relating to desktop publishing. I will integrate the content of my \TUG\ 2019 presentation into the paper based on my \TUG\ 2016 presentation, available at \url{https://tug.org/TUGboat/tb37-2/tb116walden.pdf}. Before too long, the draft of the expanded paper will be at \url{http://walden-family.com/texland/x-tug2019.pdf}.}
