Chicago Style is a popular citation and formatting system used primarily in the humanities, especially in disciplines like history, literature, and the arts. It provides guidelines for writing, including how to structure papers, format footnotes, and create bibliographies. This style emphasizes clarity and consistency, making it easier for readers to follow the author's arguments and sources. One of the key features of Chicago Style is its use of footnotes or endnotes for citations, allowing readers to find sources without interrupting the flow of the text. Additionally, it offers two systems: the Notes and Bibliography system, commonly used in the humanities, and the Author-Date system, often preferred in the sciences.
