Support for additional citation styles is available by request.

Your professor may have specific or unique instructions for citing sources. Always use the instructions they give you, even when they conflict with the citation style guidelines.

No online or computerized citation tool is perfect. It is up to you to check the accuracy of your citations before submitting research papers or other class assignments.

Plagiarism and Integrating Source Material into Your Writing

Citing your sources is required when you quote another person directly, when the information you are using is not common knowledge, or whenever you quote, paraphrase, or summarize another author’s information.

Not citing your sources is plagiarism and violates the college’s Academic Honesty policy.

The Learning Center’s Plagiarism, Integrating Source Material, and Roadmap for Writing Essays handouts provide additional information about writing with sources.
