The Gospel Pedlar has posted the Introduction and Postscript to Verduin's The Reformers and Their Stepchildren here.
This book is a must read. He doesn't get everything right, but just let it wash over you, so to speak. For Reformed people it is an eye-opener. If you're interested in any of the things I'm writing about here in relation to Constantinianism, then you'll want this volume and you won't be disappointed.
P.S. It's not just about the Anabaptists. I'm not an Anabaptist in terms of baptism. There are bigger issues here.
