October is National Stamp Collecting Month. It is also American Archives Month, and archival institutions around the nation are taking this opportunity to promote their collections. In Wisconsin we’re using the theme Postcard Wisconsin to celebrate Archives Month. Archival records can be valuable resources for the philatelic researcher and we hope to highlight selected archival collections in future posts on this blog. The National Postal Museum Library is home to a number of special archival collections and it is beginning to develop online finding aids for these collections. One of the collections is the archives of the Third Assistant Postmaster General’s Office which contains documents related to the design and production of U.S. regular stamp issues from Scott #1 (1847) to Scott #2532 (1991) as well as ‘back of the book’ issues (airmail, postage dues, postal savings, federal duck stamps, and postal stationery) for roughly the same period. On a personal note, I bring stamps and archives together with my collection of archives and archivists on postage stamps.
