Zotero

Zotero is a free research tool for people who collect, organize, annotate, cite, and share research. It is available for Mac, Windows, Linux, iOS, and Android. Users can organize research items into collections, assign keyword tags, and create saved searches that automatically gather relevant materials as they work. Zotero generates references and bibliographies for text editors, including directly within Word, LibreOffice, and Google Docs. Optional synchronization keeps files, notes, and bibliographic records updated across devices and makes synchronized research accessible through a web browser.
