Zotero is, at the most basic level, a reference manager. It is designed to store, manage, and cite bibliographic references, such as books and articles. In Zotero, each of these references constitutes an item. More broadly, Zotero is a powerful tool for collecting and organizing research information and sources.
Zotero is a free, easy-to-use, open source tool to help you collect, organize, cite, and share research. Zotero is the only software that automatically senses research on the web. Zotero helps you organize your research any way you want. You can sort items into collections and tag them with keywords. Or create saved searches that automatically fill with relevant materials as you work.
Zotero instantly creates references and bibliographies for any text editor, and directly inside Word, LibreOffice, and Google Docs. With support for over 9,000 citation styles, you can format your work to match any style guide or publication. Zotero can optionally synchronize your data across devices, keeping your notes, files, and bibliographic records seamlessly up to date. If you decide to sync, you can also always access your research from any web browser. Zotero lets you co-write a paper with a colleague, distribute course materials to students, or build a collaborative bibliography. You can share a Zotero library with as many people you like, at no cost.
