How did we eat in the past? Michigan State University’s Feeding America: The Historic American Cookbook project digitizes 76 historic cookbooks (out of the collection of 10,000) from the late 18th century to the early 20th century. The archives are searchable, there is a brief glossary of culinary terms, and an incredible photograph library of their cooking utensils and kitchenware collection is included. You can search the digitized holdings by alphabetically by title, image, ingredients, dish, or topics like temperance, military cooking, or cooking for children.
For archivists, the site also describes the project and the digitization process.
