Yeah that would be useful sometimes, I use it a lot for keeping tabs on my references and bibliography when i am writing essays. OU at the moment is a real struggle, The reading is very dry and has not inspired me at all. Hopefully next module will be better.
I use the referencing stuff built in to Word to manage... references. I tried End Note once, and another thing that I can't remember the name of, but it seemed far too complicated for my basic needs.
