I keep thinking about a talk I saw by Ferdinand Ulrich, archivist of early digital fonts.
Ulrich showed how institutions have huge archives, with reports and books and correspondence of people from the type world exploring how analog typography could be used on the computer. The birth of digital typography!
You could read all the back-and-forth that went into establishing standards, exporing new ideas, creating prototypes. When the world wide web became common, much of this obviously moved to the digital world. Until ~2010 people were still in the habit of printing and archiving important mails, but after that?
