EasyBib is a free Automatic Bibliography Composer – that a friend sent over for me to have a look at. (I tried to Digg It but someone beat me to it!) This would have been a helpful tool while I was doing my undergraduate degree. My School (specifically the History Department) constantly tried to get us to use proper formatting for citations. And I can remember deveral Profs who took off (what I felt) were obscene amounts of marks for the odd mistake (italicizing instead of underlining for example.) There were programs that did this automatically available, but the cost always made me cringe. At least this one is (mostly) free.Edit: After reading through comments on Digg another recommended helper for citing sources is CitationMachine.
