This section draws on The New York Times and assorted Internet references as well as Mimi Sheraton's memoir Eating My Words. A major source is The Automat: The History, Recipes, and Allure of Horn & Hardart's Masterpiece by Marianne Hardart and Lorraine Diehl, highly recommended for a fuller history of this institution, as well as for recipes for some of its signature dishes. William Grimes' Appetite City was another source.
