Old-time Presses In A Modern World

Typesetting was its own arcane art at one time; apprentices spent months learning how to properly sort type before progressing to setting. Eventually, it became second nature.

"It's like typing; you don't look at the type cases," Eckert explains.

(Incidentally, adds Chauncy, of INHP, the fact that capital letters were stored in the "upper case" and small letters in the "lower case" may have led to our use of that terminology today.)
