To learn more about Zotero and get started with installation, visit BC's main Zotero guide:
Zotero offers many citation styles for footnote insertion and bibliographies, including Bluebook. Beware that it's not great, particularly with primary legal sources, so you'll need to clean up the citations. However, it's still excellent as an organization tool, and the citations provide a starting point.
Steps: Open Zotero via your desktop app (see installation instructions above, from O'Neill Library). Select Edit from the main menu, and then choose Preferences. Click on Cite. Select the Bluebook Law Review style from the options offered.
