It's not a pbook, it's a Holmes-Ginsbook Device
“The Holmes-Ginsbook Device” , Isaac Asimov, seemingly only released in the collection Opus 100, is a fine short story about two devoted scientists and their invention of an improved document reading device, as the current state of the art made it too difficult to look at girls and smoke.
I can't remember many of the other stories in that book, but this one has stuck with me.
