In my quest to buy microfilms of old newspapers, I ended up at ProQuest, which is apparently the new parent company for what was once Bell & Howell. I was referred to this online index and ended up looking at the dissertations that can be viewed. I did a search for genealogy and got all kinds of interesting topics, including one on American Indians. http://www.il.proquest.com/ad-indivresearch.shtml http://wwwlib.umi.com/dissertations/ http://wwwlib.umi.com/dissertations/search
