What is Zotero? Zotero is a free reference manager that allows you to gather and organize your references as well as automatically create in-text citations and bibliographies in the citation style of your choice.
Zotero works on all three major operating systems: PC, Mac, and Linux. It works best with the Firefox browser, but you can download and install plug-ins for the Chrome and Safari browsers as well.
