NARA's Special Media Branch blog, The Unwritten Record, recently posted a great overview, "How to Research: Photographs Relating to WWII Army Units" by Aaron Arthur. This post is the first of a four-part series and explains how knowing a unit's lineage, campaign locations, major battles, and any prominent individuals in the unit, can offer different avenues through which a researcher might locate photographs among our holdings. It also references some of the commonly used series. Looking forward to the rest!
