"Dyke's Troubles, Remedies and Repairs of the Automobile and Gasolene Engine," 1909

In the first decade of the 1900s -- when automobiles were new -- virtually no one had the "know-how" to maintain and repair them. Some people learned through a combination of hands-on tinkering and reading books like this one. Dyke's manuals explained the workings of the new internal combustion engines -- and unraveled the mystery of how to fix them when they broke down.
