The American Philatelic Center operating hours over the Christmas and New Year's holidays will be adjusted. This will allow employees of the American Philatelic Society and the American Public Research Library to spend time with their families and celebrate the season. 

This year, in recognition of all the hard work of our staff and another great year for APS membership, the APS will close for Christmas Eve on 24 December 2021 and reopen on Monday, 3 January 2022.
