RefWorks is a web-based program that allows you to manage your bibliographic citations and easily create works cited pages. Many online databases and journals allow you to import a citation into RefWorks with just the click of a button.
Refworks is FREE for you to use as a student, and you can maintain access to your account after you graduate. Visit the RefWorks Guide for information on creating an account.
The Write-n-Cite plugin for Microsoft Word allows you to insert citations as you write your paper, and automatically formats in-text and bibliography references.
