Zotero: Zotero is a free “bibliographic citation management” software that allows you to save, collect, manage, cite, and share research sources. It works inside your browser enabling you to save citations easily as you do your research. You can also take notes in Zotero, allowing you to store your reactions to your source right next to its citation. Use the Zotero Word Processor plugins to easily cite your sources and create a bibliography while you work. (NOTE: Though Zotero will save you lots of time in the creation of footnotes/in-text citations, and bibliographies, it is always a good idea to proofread your work).

To use Zotero, you will need to download two things:
(a) The Zotero Application Itself
(b) A Connector to allow your browser to save citations to Zotero

 Both of these are available from the Zotero download page
