The Museum of American War Letters is offering not just glimpses of the letters, but audio of tapes and other communications sent back home by soldiers, sailors, airmen and Marines. Right now, it’s mostly focused on Vietnam, but it plans to expand, and it’s open to anyone who wants to visit, virtually. “The institution has no street address — it’s a virtual, interactive museum that was designed to give visitors the sense of traveling through a physical building with a floor, ceiling and walls.” – The New York Times
