I may be late on this... I just read about The Researching Librarian http://www.researchinglibrarian.com/ in C&RL News (April 2009). It's part of a large article by Laurie Putnam, "Professional writing and publishing". What an interesting site! It's geared for librarians who need to research and publish for tenure or job advancement. The site feels sort of amateurish but it's great to know that resources are out there... other than ACRL's own mentor program.
I looked over this site again. It's nothing new, unfortunately.
