Tony D:  Are you going to include Chief Buffalo's claim in the Point of Rocks section?  That's an important part of Duluth history that I never learned until PDD came along.  

J-Buck:  Here are a few books that can get you started. 

The Mishomis Book by Edward Benton-Banai was written for middle-school-aged kids, but it happens to be just about at my level.  Seriously I learned a lot from it.  

Indian Givers, by Jack Weatherford and its companion "Native Roots" discuss Native American people generally but include sections on the Ojibwe fur trade and how it transformed the world's economy. Ever heard of John Jacob Astor?  He did a lot more than go down with the Titanic and he couldn't have done any of it without Native American people from our region.  

The Four Hills of Life, by Thomas Peacock and Marlene Wisuru is another book designed for kids but adults can get a lot out of it.  Thom Peacock is a Fond du Lacker who has written several books. He also edited and wrote a few of the oral histories in A forever story: the people and community of the Fond du Lac Reservation. Those few books should be a start for you.

Great video Jbuck! 
When I started reading Duluth history, I started with a book about the explorers. The writings are biased, somewhat inaccurate, and a little clumsy; however, they are the first hand accounts of what MN and Duluth were like before any other Europeans hit the North Shore of Lac Superior. 

See Radisson's journals (http://en.wikipedia.org/wiki/Pierre-Esprit_Radisson), Sir Duluth's writings, and Father Hennepin's journals (although only portions are relevant). There's nothing like reading the primary source. 

But from the title, Lost Duluth sounds fantastic!!!! Excited to see more Tony D!

Sometimes books which focus on a specific subject offer some good history in the context. One book that fits this description is Daniel Lancaster's book, John Beargrease: Legend of Minnesota's North Shore. The book is published by Duluth's own Holy Cow! Press (www.holycowpress.org/).  If you can't find it at our local bookstores, Amazon will be happy to help:
