Since 1930 the Society has encouraged philatelic study through voluntary membership in specialized committees and study groups. Some committees specialize in specific stamp issues like the Washington-Franklin heads, the Prexie or the Liberty Series. Other committees study specialized areas of U.S. philately such as Plate Numbers and Marginal Markings, Private Vending and Affixing Perforations, Booklets and Panes, and Luminescence. Our research is made available through published books, research papers and articles in our monthly journal, The United States Specialist.
