Publishers Street & Smith of New York published over 1,000 Nicholas Carter books, none of which carried author credits, although it is known that the first was by John R. Coryell, and many of the earliest volumes were by Frederick Van Rensselaer Dey, Thomas C. Harbaugh and Eugene T. Sawyer.

Novels featuring Carter continued to appear through the 1950s, by which time there was also a popular radio show, Nick Carter, Master Detective.
