These are our links to all manner of websites, some more helpful than others. The presence of any link here does not indicate an endorsement of any kind: this set of links is meant to be of use for university and college faculty teaching in this field. We will be expanding the number of links we offer, and would be delighted to receive any suggestions. If you would like to help us in this effort, or if you have trouble connecting to one of these sites, please let us know by email at studies@esoteric.msu.edu. This is not a comprehensive set of links, by any means, but it is organized more or less according to historical periods. The research for this site was done by Joshua Strozeski, our previous archivist, and by Aaron Miller, our current excellent archivist.
