Citation styles are standardized methods for acknowledging sources used in academic writing. They provide a consistent format for presenting information about books, articles, websites, and other resources. Common citation styles include APA, MLA, and Chicago, each with specific rules for formatting citations and references. These styles help readers locate the original sources and give credit to the authors, promoting academic integrity. Different fields of study often prefer specific citation styles. For instance, APA is widely used in the social sciences, while MLA is common in the humanities. Understanding and using the appropriate citation style is essential for effective communication in academic and professional writing.
