Citing Your Sources
5.2 What’s Included in a Citation
There are thousands of citation styles, and they all have different guidelines for how to format citations. However, most of them include the same types of information about a source.
In-text Citation
An in-text citation goes in your paper at the point where you quote, paraphrase, or summarize an idea from an information source. The elements and formatting will vary depending on the style you are using.
For example, an MLA-style in-text citation includes the author name(s) and the page number of the information:
An APA-style in-text citation includes the author name(s) and the year of publication:
Some other citation styles, such as Chicago’s notes-bibliography system and ACS style, use footnotes or endnotes to indicate citations.

The elements included in a reference and how they are formatted will vary depending on the style. Still, a reference in any style answers four questions about an information source.
