We have created a research guide to an oral history collection held at the St. Louis Community College– Florissant Valley Library. The guide has PDF transcripts of more than 140 interviews with American Indians conducted during the mid-1970s. I think this material might be of interest to family historians.
Here’s the Worldcat link and a direct link to the guide. A Worldcat search for the name of one of the “memoirists” in this collection will pull up the record that has a link to the guide. PDFs can be accessed from the guide.
