Chicago
Chicago style, also known as the Chicago Manual of Style (CMS), is a widely used citation and formatting style in various disciplines, particularly in history, business, and the humanities. Chicago style offers two primary citation systems: the Notes and Bibliography system, commonly used in the humanities, and the Author-Date system, typically used in the sciences and social sciences. The Notes and Bibliography system uses footnotes or endnotes for in-text citations, along with a bibliography at the end, while the Author-Date system uses parenthetical citations in the text and a reference list. Chicago style is valued for its flexibility and thoroughness in handling different types of sources.
