Greene, was published in 1912 by The Arthur H. Clark Company of Cleveland, Ohio.

Among Dickerson's other publications were Boston Under Military Rule (1768-1769) as Revealed in a Journal of the Times (1936); and The Navigation Acts and the American Revolution (1951).

Writing in the November 1952 issue of the Journal of Southern History, Leonard W. Labaree wrote that, "The book should be prescribed reading for teachers and especially for writers of textbooks (p. 543).

Dickerson was the last surviving charter member of the Mississippi Valley Historical Association, and participated in both the first and fiftieth meetings of that organization.
