Generally, yes, citations are placed in parentheses to differentiate them from the text. This is common in many styles, such as:
* APA: (Author, Year)
* MLA: (Author Page Number)
* Chicago: (Author Year, Page Number)
However, some styles use different methods:
* Footnotes/Endnotes: Citations are placed at the bottom of the page or at the end of the document, numbered sequentially.
* Harvard: Author (Year) is placed in the text itself.
Ultimately, the best way to determine the correct placement is to consult the specific style guide you are using.
