How To Cite Sources In Chicago Style? Made Easy

The Chicago style of citation is one of the most widely used citation styles in academic and professional writing. It provides a comprehensive guide for citing sources in research papers, theses, and other written works. In this article, we will delve into the world of Chicago style citation, exploring its intricacies and providing a step-by-step guide on how to cite sources with ease.
Introduction to Chicago Style

The Chicago Manual of Style (CMS) is a style guide that provides guidelines for writing, editing, and citation. It is widely used in the humanities, social sciences, and natural sciences. The Chicago style offers two main citation styles: the author-date system and the notes-bibliography system. The author-date system is commonly used in the physical sciences, while the notes-bibliography system is used in the humanities and social sciences.
Author-Date System
The author-date system is a citation style that uses parentheses to enclose the author’s last name and the year of publication. This system is commonly used in the physical sciences, such as physics, chemistry, and biology. For example, a citation for a journal article might look like this: (Smith 2020). The corresponding reference list entry would include the author’s name, title of the article, title of the journal, volume number, issue number, page numbers, and the year of publication.
Source Type | Reference List Entry |
---|---|
Journal Article | Smith, John. 2020. "The Effects of Climate Change." Journal of Environmental Science 10 (2): 12-20. |
Book | Johnson, Jane. 2019. The History of Science. New York: Random House. |

Notes-Bibliography System
The notes-bibliography system is a citation style that uses footnotes or endnotes to cite sources. This system is commonly used in the humanities and social sciences, such as history, philosophy, and literature. For example, a citation for a book might look like this: 1. The corresponding footnote or endnote would include the author’s name, title of the book, publication information, and the page numbers.
