I have been working on putting together ENGR Wiki an engineering research based Wiki that is now accessible at Ohio University Alden Library. The Wiki has reached a good enough size now that I can release it to the public. I hope you find it interesting though it will be most useful to engineering researchers from the Ohio University community.
The Wiki has a breakdown of useful databases by engineering discipline that are taught at the Russ College of Engineering. It also has research guides about patents, standards, and other topics. It is also the home of the OU Engineering Toolbar.
