If you’re the type of writer that uses facts of some sort, this website my be your new best friend. It’s called Zotero and it’s a free citation management program. Those who have forked out the cash for EndNote may appreciate this site. I haven’t tried it out yet, but the home page claims that it works as a Firefox extension. So you can save citations from the websites you’re searching in real time.
