ProQuest RefWorks is a citation management tool that assists researchers in gathering, organizing, annotating, and citing their sources. Accounts are free to anyone with an SU email address (students, staff, faculty).

Please note that citation tools like RefWorks are only as perfect as the data they are extracting from resources -- you should always double-check your citations to make sure they are correct.
You always have the most control over the accuracy of your citations when you do it by hand using the selected style manual (above).
