Citation style refers to a standardized method of acknowledging sources used in academic writing and research. Different styles, such as APA, MLA, and Chicago, provide specific guidelines on how to format references, in-text citations, and bibliographies. These styles help maintain consistency and credibility in scholarly work. Using a citation style is essential for avoiding plagiarism and giving proper credit to original authors. Each style has its own rules regarding punctuation, capitalization, and the order of information, making it important for writers to choose the appropriate style based on their discipline or publication requirements.
