Citation Formats Resource

From the library guide on citation management, these are the most common formats for citing sources. If you are unsure which style to use, ask your professor.

Citation Formatting and Management Tools

It can be difficult to keep up with citation styles and the changes within and among them. To take the guesswork out of the process, there are a number of citation-management software programs. This type of software will format your bibliography and footnotes for you. It’s also a great way to keep track of all the information you’ve found.

We especially recommend RefWorks (Internet-based and free to current Cornell students, staff, and faculty) and Endnote (desktop-based).

You may also wish to refer to the Annotated Bibliography Tutorial.

For electronic and online materials, include a stable URL or database name and include the author, title, and date published where available. For undated materials, include the date the resource was accessed.
