I am struggling with an historical question. Can anyone point me to some resources about the early history of type cases? I've consulted Pryor's HISTORY OF THE CALIFORNIA JOB CASE, and of course I have read Moxon. But I wonder if anyone out there has some citations that talk about the earliest decisions about the lay of the case. I am especially interested in how the lower case lay was arrived at.
I am interested in letter counting practices in general, and I think there is a story here. If you have any info on letter counting in general (sources on Gematria, for example) I'd be open to that as well.
I have always gone back to Alembic Press's Typecase Lay Selection: http://www.alembicpress.co.uk/Alembicprs/SELCASE.HTM
Also I believe Harry Carter's A View of Early Typography: Up to about 1600 has some background on case layout. Updike's History of Printing Types would be my third go-to book.
Thanks! RIT, as always, is the fount of all typographic wisdom. Caxton's case lay is CRAZY!
