What Zotero Does
Zotero
(pronounced "zoh-TAIR-oh") is a Firefox addon that collects, manages, and cites research sources. It's
easy to use, lives in your web browser where you do your work, and best of
all it's free. Zotero allows you to attach PDFs, notes and images to your
citations, organize them into collections for different projects, and create
bibliographies.
It automatically updates itself periodically to
work with new online sources and new bibliographic styles.
