Is a parenthetical reference in the document text that credits source of quotation or information used document?

Yes, a parenthetical reference within the document text that credits the source of a quotation or information is a common method of citing sources. It's often referred to as an in-text citation.

Here's why it's important:

* Academic Integrity: It acknowledges the original author's work and prevents plagiarism.

* Clarity: It helps readers understand the source of the information and allows them to verify its accuracy.

* Research: It provides a trail for readers to follow if they wish to learn more about the topic.

Example:

"According to a recent study, 'the use of social media has a significant impact on teenagers' mental health' (Smith, 2023)."

In this example, "Smith, 2023" is the parenthetical reference that indicates the source of the quoted information.

Note: The specific format of the parenthetical reference may vary depending on the style guide being used (e.g., APA, MLA, Chicago).
