(pronounced "zoh-TAIR-oh") is a free research tool created to help collect, organize, share, and cite sources.
Zotero was developed primarily as a Firefox plugin. It has since been integrated with Chrome, Opera, and Internet Explorer browsers, and made available as a standalone software. Browser integration makes it easy to save and annotate sources while searching online. Zotero was developed at the Roy Rosenzweig Center for History and New Media at George Mason University.
