This is where you can start...
The recovery of the Anabaptist Vision
If you are like me you may not even heard of the Anabaptists before. And when I was introduced to them I was like the disciples at the Ephesus before the apostle Paul, ?We have not so much as heard whether there is a Holy Spirit.?
Started off my journey with half translated(!) work of Verduin, the Reformers and their Stepchildren, yet I was still so much hungry. And eventually bought the book, the Martyrs Mirror, my second best investment, and many others. However I often wondered what their true philosophy and theology were and are. I have read many stories and their godly deeds yet not read much on their doctrines. And this book is one of my treasure that I found.
Interestingly enough this book has been written by various Anabaptists(?) of these days tributting to Harold S.Bender (some of you might thought this is where Herald Press came from but like my mistake it was Herald not Harold, however you are right about Judson Press and Erdmans). This book is consisted with over twenty essays from the great Anabaptist theologians and professors.
Look at the names and be impressed. Besides Harald S. Bender, Robert Friedmann, John H. Yoder, Franklin Littell, John C. Wenger, John S. Oyer, Ernest A. Payne and Roland H. Bainton. Wow! I?ve read at least one of their books and these are great and great authors and orthodox thinkers.
Therefore I definitely believe this is a good place to start for Anabaptist and through the study of the Church History, for the past-Reform section will be greatly beneficial.
Glory to the LORD for the day of His sacrifice, Amen.
