Deep Blue is the University of Michigan's permanent, safe, and accessible service for representing our rich intellectual environment. The primary goal of Deep Blue is to provide access to the work that makes Michigan a leader in research, teaching, and creativity. By representing our scholars, from faculty through students, as individuals and as members of communities, Deep Blue provides a framework for preserving and finding the best scholarly and artistic work done at the University.

I found the good site of scholar theses, articles, dissertations this afternoon. I introduce it to everybody, who researches seriously. You can find some rare documents in their database. Maybe you can download some of them.
