American Topical Association Study Unit Program
The American Topical Association is composed of members who specialize in thematic or topical philatelic collecting. Those who share a specific topic band together to form "study units." These units promote their specific topic and encourage research on that topic. These groups then affiliate with the ATA to receive various benefits including a free review of their journal in Topical Time, the bi-monthly publication of the ATA. The units are eligible for a free meeting room during the annual National Topical Stamp Show (NTSS). The study unit receives free publicity in ATA listings, literature and press releases.

In return, each study unit agrees to to file an annual report with the American Topical Association, listing its officers and including a list of the unit's membership. The unit is encouraged to promote membership in the ATA by individual members.
