New to Typophile? Accounts are free, and easy to set up.
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 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.
