Michael zur Muehlen is an Assistant Professor of Information Systems at Stevens Institute of Technology in Hoboken, New Jersey. He has been so kind as to offer a free download of his book, Workflow-based Process Controlling – Foundation, Design, and Application of Workflow-driven Process Information Systems. If you love it, and do not want to go blind reading a 300 page PDF, you can purchase it. The publisher’s site is in German and the book is priced in Euros, so good luck with that.

If you insist on going blind, like me, set your Acrobat zoom settings to “fit visible” and you might make it half way through before you eyes burn out….
