Official Automobile Blue Book, Volume 9

This 1920 Automobile Blue Book (Volume Nine) covers Oregon, Washington, British Columbia, Idaho, and western Montana with extensions into Wyoming, Utah, and northern California. The publication serves as a motorist's encyclopedia, providing complete motor road maps, running directions at every fork and turn with mileages, points of local and historical interest, state motor laws, hotel and garage accommodations, ferry and steamship schedules and rates. Sample content includes Route 642 from Wallace, Idaho to Spokane, Washington (88 miles), describing road conditions (gravel, rough mountain roads, macadam, and concrete sections) and landmarks including Coeur d'Alene Lake. City entries detail hotels, garages, battery services, and drug stores. The book includes detailed maps of national parks (Crater Lake, Glacier, Mt. Rainier, Yellowstone) and multiple street maps of towns. Accompanying advertisements promote Syra-Cord tires, Hood tires, and Goodell-Pratt motor tool sets.
