Zotero is a free open-source citation management tool designed to help you collect, organize, cite, and share your research. With Zotero, you can attach screenshots, PDFs, images, and notes to your citations, create bibliographies from a wide array of citation styles, and share your bibliographies with the Group Library feature.
Zotero Data Security: "Zotero was created with the philosophy that your research data belongs to you and should be kept secure and private by default. All Zotero software is open-source and can be audited for security and privacy practices. Unlike many cloud-based tools, the Zotero desktop application is a local program that runs on your computer and saves all research data locally by default. Unless you explicitly set up syncing, your research data never leaves your computer. If institutional policies prevent uploading of data to third-party servers, Zotero can always be used locally without syncing any data, but syncing is required to use group functionality."

Tiffany C. Esteban created this Zotero guide and updates it regularly. She works as the Digital Humanities Associate at the Humanities and Social Sciences Library West, where she does consultation and instruction sessions focused on digital humanities. She uses Zotero herself and recommends it to students, researchers, and instructors who are looking for a citation management tool that centers their needs, data, and privacy. She also supports those who choose not to use citation management tools in their work for whatever reason.
