If your profile is still accurate, you are in a fantastic place for resources.
Right there, in Buffalo, is "The Sausage Maker":
1500 Clinton St, Buffalo, NY 14206
To your exact question:
"Great Sausage Recipes and Meat Curing" by Kutas is a very good resource
I also like to refer to "Charcuterie" by Ruhlman and Polcyn.
