E.P. Ingersoll began publishing The Horseless Age monthly in November 1895. It was the first English language publication devoted exculsively to the motor car. 1 Originally a monthly, after October 1899 it was printed weekly. 2 Ingersoll began the first page of the first issue with these words:
"WE present to the trade and the public the first number of The Horseless Age, a journal which will be published monthly hereafter in the interest of the motor vehicle. The appearance of a journal devoted to a branch of industry yet in an embryonic state, may strike some as premature, and the somewhat desultory character of this number may provoke criticism in some quarters. But those who have taken the pains to search below the surface for the great tendencies of the age, know what a giant industry is struggling into being there. All signs point to the motor vehicle as the necessary sequence of methods of locomotion already established and approved. The growing needs of our civilization demand it; the public believe in it, and await with lively interest its practical application to the daily business of the world." 3

By the time The Horseless Age ceased publication and was absorbed into Class Journal publications (publisher of Motor Age) in May 1918 the future path of the automobile had long since been established. 4 But in the early issues nothing was settled. The power source could be steam, electric, kerosene, gunpowder, compressed air, springs, or even gasoline; the steering wheel had not yet obsoleted the tiller, pneumatic tires had not yet proven practical.

Most of the issues are available on-line at the Haithi Trust, and many of these scans have been made available in printed form (albeit in a reduced form factor) on Amazon.
