Links
Here are some links to other philatelic sites I find interesting and useful, with some annotations.
Society Websites

American Association of Philatelic Exhibitors: If you are an exhibitor, or want to be one, join this organization.
United States Philatelic Classics Society: Focus on 19th century US. Tremendous resources online, including digitized books such as the American Stampless Cover Catalog.
United States Stamp Society: US specialty society with focus on the bureau issue of 1894 and later. Excellent for collectors of 20th century material.
