Shugart's letters are not on-line, but detailed a listing of them is at the Indiana State Library's web site (Manuscript Section, Indiana Division). I think that if you Googled "William L. Shugart Letters" this page can be found. I ordered copies of 3 letters which covered the period I was interested in, they were useful.
