Citing a book is a crucial step in the process of academic writing. It is important to credit the original source of information to maintain the integrity and reliability of your work. There are several citation styles, each with its own set of rules, that are used in academic and professional fields. This article provides an overview of four popular citation styles: APA, MLA, Chicago, and Harvard.
