NARA has several regular blogs which are listed here: https://www.archives.gov/social-media/blogs, of which The Text Message, The Unwritten Record, Pieces of History, and Rediscovering Black History, will be of the most interest to genealogical researchers.

In addition, NARA’s designated subject matter experts (SMEs) also write blog posts several times a year that can be found on the History Hub. Recent examples include WWI Enemy Alien Registrations, Permits, and Enforcement by Elizabeth Burnes; Researching World War II Bombing Aerial Photography by Corbin Apkin; and NARA Records Pertaining to Free Blacks in the Antebellum Period (1763-1861) by Damani Davis.
