Advertising cookbooks are a means for food companies and appliance manufacturers to promote use of their products by providing recipes and home hints. Whereas early examples often are simple and printed in black and white, later booklets increasingly were attractively printed with color art or photographs. Advertising cookbooks provide information about American foodways, kitchen technology, gender roles in the household, and much more. The Title Page and Table of Contents or Index for each cookbook have been transcribed and are searchable.
