Zotero is a research management software program that enables you to save and organize your references, then output them as in-text citations, footnotes, and bibliographies through a word-processing software plugin.

Zotero is:

• great for undergraduates as well as seasoned researchers
• especially good for saving non-traditional, web-based references
• aimed at humanities and social science research
• easy to learn
