This trilogy by John A. Jakle and Keith A. Sculle examines, in turn, service stations, roadside eateries and motels/inns. If you’re interested in American road culture, I challenge you to find more information in one place on any of these subjects.
The three I’ve read in the authors’ Gas, Food, Lodging series have all been excellent, and I can recommend all three. They’re a little more academic than some books out there, which makes sense because the authors are both professors: Jakle specializes in geography and landscape architecture at the University of Illinois at Urbana-Champaign, while Sculle teaches history at the University of Illinois at Sprinfield. Each volume is packed with more information on chains and trends, along with statistical information, than you’ll find most places:
