Citation Managers make creating references easier by automatically pulling in citations from databases, library catalogues and selected search engines. Citations can then be automatically added to your work formatted in the style you prefer.
Zotero is a free bibliographic citation management software that allows you to save, collect, manage, cite, and share research sources. Zotero is available either as a Firefox extension or as standalone software that works with Firefox, Chrome and Safari browsers. It works right in your browser, making it easy to save you citations while you search.
Use the Zotero word processor plugins to easily cite your sources and create a bibliography while you work.
