WMNU-TV in Michigan has posted a viewer's guide (PDF) for the 2004 award winning documentary called "The Enemy in Our Midst: Nazi Prisoner of War Camps in Michigan's Upper Peninsula."

They also offer a booklet called POW Camps in the U.P. (PDF), which contains original articles cited in the documentary.

According to their site:

From 1944 to 1946, the German prisoners called five POW camps in the Upper Peninsula home: Camps AuTrain and Evelyn in Alger County, Camp Raco in Chippewa County and Camps Sidnaw and Pori in Houghton County. Brought in under a cloak of secrecy by the U.S. Army, the prisoners eventually encountered local residents, who were reluctant to accept the POWs.

The project, which took two years to complete, contains many scenes shot throughout the Upper Peninsula. Also included in the 161-minute documentary are hundreds of historic photos, vintage film and interviews with local residents who had encounters with the POWs.
