As a scholar, you cite sources:
Your professor may require that you use a certain citation format, such as APA, MLA or Chicago Style. If they do not require a specific format, select the format you are most comfortable with and use it consistently throughout your paper.
For more information, see the following sources:
Note: There are many citation style cheat sheets and guides available online. Use these with caution. Both APA and MLA have recently been updated, and many online cheat sheets do not reflect these chages. In addition, many of these guides are not complete, and can contain errors.
When in doubt, consult the official syle manual. These also contain information how to format a paper (headings, spacing, font, language, etc).
