Zotero is a free research tool that helps you collect, organize, and analyze research and lets you share it in a variety of ways. Zotero includes the ability to store author, title, and publication fields and to export that information as formatted references. It can also organize, tag, and search in advanced ways.
Zotero interacts seamlessly with online resources: when it senses you are viewing a book, article, or other object on the web, it can automatically extract and save complete bibliographic references. It runs both as a web service and offline on your personal devices.
