Publication citations are references that acknowledge the sources of information used in academic and research work. They provide essential details about a work, such as the author, title, publication date, and where it can be found. This practice helps readers locate the original sources and gives credit to the original authors, promoting academic integrity. Citations are formatted in various styles, including APA, MLA, and Chicago, each with specific rules for how to present the information. Proper citation is crucial in scholarly writing, as it allows for the verification of facts and supports the credibility of the research being presented.
