In 1938 and 1939 the Detroit Free Press ran a series of articles penned by E. L. Warner Jr. on the golf courses in the Detroit area. The articles contain a good bit of information on the formation of each club and their architectural histories, and although not exactly contemporaneous they are close enough in time to be considered fairly reliable.
