If you’re looking for a way to organize all the information you find and research you do online, and you’ve had enough with bookmarking, copying and pasting, and cobbled-together techniques not cutting it, Zotero is a comprehensive information manager for Firefox.
Zotero is, at its heart, a citation manager. It was designed to facilitate research and to make organizing and including that research in essays and publications pain free. As such, it’s an excellent tool for any scholar, researcher, or student to have in their toolbox. Its utility extends well beyond preparing to write a paper, however, as it allows you to grab nearly anything off the web and insert it into the Zotero system.
