While he has not authored any books in the traditional sense, he has created several artist's books which are considered important works in the art world. Some of his most notable artist's books include:
* Twentysix Gasoline Stations (1963)
* Various Small Fires and Milk (1964)
* Some Los Angeles Apartments (1965)
* Every Building on the Sunset Strip (1966)
* Royal Road Test (1967)
These books combine text and images in a unique way, often featuring simple, everyday subjects like gas stations, fires, and apartments. Ruscha's work explores themes of urban landscapes, language, and the American West.
It's important to note that Ruscha has also contributed texts to exhibition catalogs and other publications, but these are not considered authored books in the traditional sense.
