Why cite your sources?

You must document the sources you used in order to give recognition to the original author. Whether paraphrasing or using direct quotes, ideas that are not your own must be cited.

How do I choose a style?

Your instructor will provide you with the preferred style for your course. They may also have specific formatting instructions. Ensure you remain consistent with style and formatting, and provide enough information for the reader to identify the work or cited material.
