Award-winning Congress Books have been published annually since the founding of the American Philatelic Congress in 1935. A complete set of these books contains hundreds of scholarly articles pertaining to various aspects of philately. Among the many articles are subjects such as specific stamp issues, postal markings, and postal history. These books provide the philatelic researcher the opportunity to present written, original research papers for the philatelist. Articles are contributed without financial reward; many of these writers are first-time authors.
A copy of the annual Congress Book is sent to each member. Society news is conveyed to the membership in periodic Congress Comments newsletters. The American Philatelic Congress does not compete with any other societies as it is a unique organization dealing only in philatelic research and publication.
A yearly convention is held in conjunction with the American Philatelic Society StampShow stamp exhibition. For the convenience of members, the site is selected geographically so that various areas of the country are considered as convention sites. As part of the agenda of each convention, various authors present their articles from the current Congress Book.
Collectors are invited to contribute articles of lasting philatelic interest for the annual book.
The American Philatelic Congress is affiliate #AF 0139 of the American Philatelic Society.
