I think the Works of Peter Martyr Vermigli would be a great asset in Logos to students of Church History, Systematic theology and the Reformation!
Here a some of links to Peter Martyr Vermigli and his works:

This would be a good source for the student of church history, and particularly of the history of reformed thought. He comes up fairly frequently for mention in D'aubigné History of the Reformation in the Time of Calvin (http://www.logos.com/product/4559/history-of-the-reformation-in-europe-in-the-time-of-calvin) and Muller Post-Reformation Reformed Dogmatics (http://www.logos.com/product/4463/post-reformation-reformed-dogmatics).
