The National Newsletter first appeared in the February 1970 issue of the Journal as a simple stapled add-in that focused on Society news and information. In February 1978 it changed into a physically separate 16-page supplement under Editor Frank Shinn. In 1991, the National Newsletter was transformed into the Bulletin in a more expanded format.

Many members contributed news items, photographs and other materials which make for interesting reading even today. All 126 back issues of the National Newsletter have been digitized, so this historical record is available for everyone who would like to learn more about the activities of the Society in the years leading up to its Centenary in 1990.
