Thought I'd pass this along since I am involved in developing it -- a specialized search engine that includes leadership and management related material only. No spam, no tricky sites, only content rich sites.

It's in development but if you want to test it out it's at http://researchprofessional.or...leadership/index.htm

There's a similar one on training, development and learning which is a great way to find journal research articles and abstracts. It's at http://researchprofessional.org/training/index.htm

Feel free to let others know, and if send along comments, since development is ongoing.
