The Army Air Force Exchange Service not only has a webpage/online shopping mall, but the service itself is interested in archiving its 100+ years of history.  The page dedicated to this contains not only photographs and facts, but an ongoing call for anybody with relevant experience and documents to step forward and share.  It’s a very good idea, partly because when one lives overseas, the commisary, PX/BX, and all the other services really are a important part of day to day life.
