The American Philatelic Society (APS) is the largest non-profit philatelic organization in the world. As of 2018, they have about 30,000 members in approximately 110 countries. Both the membership and the focus of the society are Worldwide.
The society was founded in September 1886, in New York City, as the American Philatelic Association, and the first president was John K. Tiffany. Their early membership roster read like a who's who of the giants of philatelic history that we recognize today. In 1908, the name was permanently changed to the American Philatelic Society. By 1940, there were over 4,000 members, including President Franklin D. Roosevelt! In 1945, the headquarters of the APS moved from New York City to State College, Pennsylvania, and in 2004, the headquarters was again relocated to nearby Bellefonte, Pennsylvania.

have been a member of the APS since 1982, and in the time since then, I have
used almost all of their services many times. There is a wealth of
information in the APS monthly journal, The American Philatelist, which
is now printed in full color. I have also found the American
Philatelic Research Library to be an outstanding source of information
over the years.
A few years ago, I began researching 19th Century Austrian Imperial postmarks for my Austrian Empire collection. It was a huge undertaking, encompassing postmarks from over 11,000 post offices, covering most of Eastern Europe and the Mediterranean. Many of the most important publications on Austrian Imperial postal history and postmarks are German language books that have been out of print for decades. A couple of them were last published at the beginning of the 20th Century! The APS had all of them, and I was able to borrow them, digitize them for future reference, and use them in the configuration of my postmark collection.
I also subscribe to several sales circuits. The circuit books usually contain nice, reasonably priced material that is submitted by other members. Other than the internet or the occasional philatelic exhibition, they have been one of the principle sources of quality material for my classical stamp collections since the 1990's.
