Nancy Tappan co-edited what is perhaps the most important newsletter on
survivalism and survivalist retreats in the 1970s, the
Personal Survival ("P.S.") Letter. It was published from 1977–1982. The newsletter included columns from Mel and Nancy Tappan, as well from
Jeff Cooper, Al J. Venter, Bill Pier,
Bruce D. Clayton, Rick L. Fines (writing as "Ross Lee"), J.B. Wood, Dr. Carl Kirsch, Charles Avery,
Karl Hess, Eugene A. Barron, Janet Groene,
Dean Ing, Alexander Jason, James McKeever,
Kurt Saxon, Bob Taylor,
Reginald Bretnor, C.G. Cobb, Carl E. Krupp, and several other writers, some under
pen names (such as "Dr. J.M. Browning"). The majority of this newsletter revolved around selecting, constructing, and logistically equipping survival retreats. Following Mel Tappan's death in 1980, Nancy Tappan took over publishing the newsletter, renaming it
Survival Tomorrow in 1983. In 1987, Carl E. Krupp became the new editor and publisher. ==Book editor==
