(For PC users, there is “the PC is not a typewriter” (https://www.amazon.com/Pc-not-typewriter-Robin-Williams/dp/0...), but that is even older, so I’m not sure it will be more useful than the original, unless your users are using WordPerfect or Ventura Publisher)
Nowadays, web designers have so many typographic tools to work with, like @font-face and lettering.js, but basic punctuation and formatting don’t get enough love.
It’s an oldie, but I think everyone working with web type should read Robin Williams’ The Mac is not a typewriter [0]. It’s just as relevant to modern web type as it was to early desktop publishing.
