Zotero is a free, easy-to-use tool to help you collect, organize, annotate, cite, and share research. At the most basic level, it’s a citation manager. It’s designed to store, manage, and cite bibliographic references, such as books and articles. In Zotero, each of these references constitutes an item. Every item contains different metadata, depending on what type it is. Items can be everything from books, articles, and documents to web pages, artwork, films, sound recordings, bills, cases, or statutes, among many others.
Zotero automatically senses research as you browse the web. Need an article from JSTOR or a preprint from arXiv.org? A news story from the New York Times or a book from a library? Zotero has you covered, everywhere.
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.
The software instantly creates references and bibliographies for any text editor, and directly inside Word, LibreOffice, and Google Docs. With support for over 10,000 citation styles, you can format your work to match any style guide or publication.
This is free and open source software.
