1. Jolliet lost map identified, 2. the Jolliet/Brown Map is a fake

I was going thru my files last month and pulled out a map that I had filed away over ten years ago. I immediately knew that it was the Lost Map of Jolliet. I had back then photocoped it from an archive collection, unaware of its significance. But since then, my understanding of the maps of the period has improved considerably. This map has never been on the internet, nor has it ever been mentioned in its historical context.

But, in the course of putting together a paper on this, planning for it to be an e-book, I happened across a discovery of equal, perhaps greater, importance to the history of the maps of the period: the Jolliet-Brown map (link below) is a fake. Holy crap !!


The following include some of the maps used in the forthcoming The Lost Jolliet Map: Found.

How the State Deals With My Plagiarism Issue

I'd been all over the place -- almost a year of effort -- with the agencies in the State of Illinois that should be expected to be attentive to plagiarism in the Journal of Illinois History. Five agencies and four or five general counsels, nearly two dozen individuals, are ennabling the plagiarism of David Buisseret and Carl Kupfer. These state officials are covering up one of the great frauds in North American cartography. Now, I've moved from the State of Illinois to the Chicago Map Society.


Ongoing: How the Chicago Map Society Deals With Plagiarism

I wrote the president, Robert Hammond, a letter explaining that Buisseret and Kupfer had used a theme in a presentation to the Chicago Map Society in which the entire presentation was based on plagiariszed material. This is not the same plagiarism by Buisseret and Kupfer as appeared in the Journal. (The current and past Newberry Library map curators, Robert Karrow and James Akerman were at the presentation.) In addition, I claimed there were numerous other academic malfeasances. I asked to show evidence for these ethical issues to the Chicago Map Society Board of Directors, with or without Buisseret and Kupfer present.

Hammond wrote back that, "the Board concluded that the adjudication of academic disputes is beyond its mission, and therefore respectfully declines your request."

Since my issues are relegated to "academic disputes," I have requested an opportunity to make a presentation to the Map Society, at a meeting. Note: my theme in my presentation to the Map Society in 2005 was "The Marquette Map Hoax." Buisseret and Kupfer rebutted with a presentation "The Great Marquette Map Hoax: a Hoax Unhoaxed."

In addition to that rebuttal, they made another "continuation" of the rebuttal to the Map Society. In addition they made two other rebuttals against me outside of the Map Society.

I am asking the Board of the Map Society that I be allowed to make a counter rebuttal. Isn't that the way that academic discourse and and give-and-take proceed?
