I completed the revision of web links for all the history simulations. Regret the long delay. I updated the documents, especially the summary of the simulation. Rather than providing individual Word documents which made for a very long list, I have placed the documents into PDF groupings. There are plenty of free software packages that can turn PDFs into Word documents. As always, your feedback is welcome. Please send to arendale@umn.edu Thanks in advance for your suggestions and feedback.
