About In-Text & Parenthetical Citations

Whenever you quote, paraphrase, or even write a sentence that is not completely original thought: You include an in-text or parenthetical citation before you close out the sentence.

In-text and parenthetical citations provide brief and relevant information for readers of your paper to know which fully-detailed bibliographic citation at the end of your paper is referenced and where.

You are not limited to only using either in-text or parenthetical citations in your paper, you can use both throughout.
