Have you explored?
Has anyone looked at www.redlightgreen.com? If so, what did you think?
After the craziness of the semester beginning is over you might want to play in http://www.A9.com and http://www.scirus.com to interesting versions of search engines.

I looked at red/green for sources for a paper for EDIT6900. Found several references that I could follow-up through ILL.
Have not slowed down in this semester!!
