A free, easy-to-use tool to help you collect, organize, cite, and share your research. Zotero allows you to attach PDFs, notes and images to your citations, organize them into collections for different projects, and create bibliographies, even from within your preferred word processor.
Zotero 5.0 offers a single stand-alone application for all users. You can add a connector/extension to use within your preferred browser.
Word processor plugins are already bundled with Zotero 5.0 and should be installed automatically for each installed word processor when you first start Zotero.
