I've been following the work of a new class project here on Wikibooks: Concurrent Engineering. I'm an engineer myself by trade, so when I see books like this pop up I take a special interest in them.
This book is being written by Professor Burke and his ME518 class from Oregon State University. It's a very new endeavor for them, but they are making good progress. There's going to be some work needed to get it cleaned up according to Wikibooks' best practices, but those can wait till the end of the semester.
It's heartening to see that new institutions are using Wikibooks, not just the handful who have used it in the past. It makes me wonder if maybe we need a "Looking for a Class Project?" link on the main page wouldn't be a very useful addition to try to get more information to the students and teachers who browse through our site.
