A citation is the complete bibliographic reference for a book, journal article, or web page.

A citation is indeed used to provide a complete bibliographic reference for a book, journal article, or web page. This means it includes essential details such as the author's name, publication date, title of the work, publisher information, and sometimes additional elements like the DOI (Digital Object Identifier) or URL for online sources.

The statement is true in its essence; however, if the choice answers suggest that citations are something other than complete references, the emphasis might be on the nuances of citation contexts, such as citation styles (APA, MLA, Chicago, etc.) or how citations can vary based on the type of work being referenced. Therefore, if "True" was an option, it likely aligns more accurately with the definition provided. It's crucial for understanding proper citation practices, particularly in academic and professional writing, to use complete bibliographic details to ensure the source can be easily located by others.
