Briefly, I'm doing some lite research working with a number of documents I can't actually read...
Don't let the name fool you, I'm no francophone; and while I can't actually read any of these Czech, French, Italian and German articles I come across, Google has been helping me suss them out with some degree of reliability.
What I'm really looking for is further information about the first footnote of [[http://www.persee.fr/web/revues/home/prescript/article/colan_0336-1500_1...|this article by René Ponot]]:
1. Martin-Dominique Fertel, La Science pratique de L'imprimerie (The Practical Science of Printing), Saint-Omer, 1723, 502 p. Index.
