Zotero is a free tool that helps you collect, organize, share, and cite your research resources. View the screenshots on the following pages for a basic tutorial of Zotero. The More Help tab has helpful links and a video overview.
Step 1: Visit Zotero.org and click "Download Now"
Step 2: Choose your download based on your browser. Zotero was created for, and works best with, Firefox. If using Firefox, you only need one download: the browswer plugin. If you use Safari or Chrome, you need two downloads: the standalone application and the browser plugin.
Step 3: Register for an account with the website. This allows you to sync your Zotero library between multiple computers, and create and join Groups to share your research with your classmates and colleagues.
