The magazine was monthly throughout its run, except that the May and June 1935 issues were combined, and there was no April 1937 issue. The initial editor was A.R. Roberts; this changed to W.W. Hubbard with the May 1936 issue, and then Harold Hersey in December 1936. There were five volumes, with six, five, six, four, and four issues respectively; the December 1935 issue was mislabelled 1/3 instead of 2/3.
