Do you read on paper, tablet, phone, or all of the above? What do you think about the respective merits of these?
I did a lot of work at PARC on the design of readable fonts, and a few years later on reading from a display (CRT) using a super-good eye tracker we had. This was prompted by "bad feelings" when trying to read from displays. The displays are better today, but I still have "bad feelings" (somewhat different) from reading from various kinds of displays, even including eInk ones. It's partly "movement" and partly memory…
The subject of paper vs digital is of particular interest to me because I volunteer with www.savenypl.org, a group created to thwart the NYPL's efforts to gut the stacks at the 42nd Street Library and sell of two branch libraries (we succeeded, mostly). I am not as skeptical of keeping books off site as some of our members, but I think many libraries are misguided in their rush to remove paper books, for reasons of both reading efficacy and surveillance. I know many technologists share these concerns. Richard Stallman was kind enough to help a few years ago (https://stallman.org/save-the-nypl.html). Now it would be good to have additional technical people weigh in on the issue of digitization / paper book removal.
May I add you to the list of such people and / or keep you posted?
