Backsheesh! or Life and Adventures in the Orient was originally published by both A. D. Worthington of Hartford, Connecticut, and A. G. Nettleton of Chicago in 1875.  A. D. Worthington republished it in 1877 under the title The Oriental World, or New Travels in Turkey, Russia, Egypt, Asia Minor, and the Holy Land, with Graphic Sketches of Life and Adventures in the Orient.

Knox combined his two trips to the Holy Land into Adventures of Two Youths in a Journey to Egypt and the Holy Land, originally published by Harper, in New York City, during 1882.  Harper later republished the book as The Boy Travelers in the Far East, Part Fourth: Adventures of Two Youths in a Journey to Egypt and the Holy Land in 1883.

The number of books in each publication run is unknown.  Yet it is possible to infer that Knox, as a successful writer, probably saw his books "selling between several hundred thousand to over a million copies of each series. . ." With each of Knox’s books selling for three dollars, "travel writing . . . was indeed a profitable enterprise."
