What is the Chicago Manual of Style (CMOS) format and citations?

• One of the recognised style manuals for academic writing is the Chicago Manual of Style (CMOS), commonly referred to as Turabian style (more on that in a moment). 
• It was first released in 1906 by the University of Chicago Press, and is currently in its 17th edition. 
• The Chicago Manual of Style offers instructions for structuring work and citing sources in certain fields, like other style manuals like MLA and APA. 
• History, business, and the fine arts are some of these disciplines. Work in the humanities, social sciences, and occasionally the sciences is occasionally formatted in Chicago style. 
• At the graduate level, Chicago is typically the recommended style manual for humanities writing, but MLA is more typical at the undergraduate level.
• The style standards developed in 1937 by Kate L. Turabian, the graduate school dissertation secretary at the University of Chicago, gave rise to the term "Turabian style." 
• These instructions served as an introduction to the CMOS and a format for graduate and college students to utilize when formatting their research papers.

Additional information-

There are significant similarities between Chicago style and the Turabian style manual, which is still issued today. Turabian style is targeted at students, whereas CMOS is more inclusive and has more rules.
