I came across an interesting web site for a project that is recording oral histories of people from Poland who were displaced during WWII and the years immediately following it. The site is called, The Polish Diaspora, 1939-50. This site doesn't actually have the audio files of the oral history interviews on it but it does have text segments of many interviews, with images. I found the clips of the participants to be very interesting reading. Who knows, perhaps one day the oral histories will be made available as podcasts.
If you know of a displaced person (DP) from Poland who would be willing to tell their story, you might want to recommend this site to them.
