As part of our ongoing efforts to make our World War I holdings available online, we are trying to find ways to include documents as well as photographs online. Because of the software we use, it is difficult to have a single WWI digital collection. So we have WWI photographs, WWI documents, WWI Posters, as well as (currently just) the Perry Douglas Erwin Letters, 1918-1919 available at this time.
This morning we uploaded Algot F. Carlson World War I Archive. Coll No. 2012.068 which has materials in both documents and photographs.
