Harvard Library has a good guide to using Zotero, a free, open-source citation management tool that makes the process of collecting and organizing citations, incorporating them into your paper, and creating a bibliography or works cited page, stress-free and nearly effortless. The Zotero guide includes links to upcoming training sessions which you register to attend.
