Julie I am definitely agreeing with you about the http://www.kosmix.com/ web site as it is really good for finding a definition, relevant facts and trusted sources. Great stuff. Also http://www.cuil.com/info/ has been great for references to a few different sites that didn't appear on google or yahoo. I think that I may be getting the hang of this finally although I may be speaking to soon. It is really good being able to share things with each other, those people doing health related topics should check out http://www.intute.ac.uk/ as a resource as i have found it very useful.
