The Career Place library site has added a list of jobfairs to their website. It is on their right sidebar about halfway down under the heading "CAREER FAIRS".
CVJS recently announced an open house at Comsys. This was kind of a jobfair with just one (big and quality) employer. It was very well run, not a mad house like employment guide's was.
The employment guide hosted two very crowded job fairs in the last two months. I'm not sure that their exhibitors were much to get excited about. Their jobfairs web site is here. They give some advice on jobfairs here. More advice on jobfairs and job searching can be found at the career center links in my previous post.
