Chicago Style was initially developed as a short style guide for the Chicago University Press. It has grown and developed into a full style guide that is used in a variety of fields, such as history and engineering.
Chicago Style allows either endnotes or footnotes for citations, or in-text parentheses; always ask your professor. The Bibliography includes full details for all sources, including archival materials and datasets.
The four elements of a bibliographic citation are:
In Chicago Notes style, the elements are ordered: Author, A. Title in Title Style. Source Title. Place: Publisher. Date. https://doi.org/#
In Chicago Author-Date style, the elements are ordered: Author, A. Date.Title in Title Style.Source Title. Place: Publisher. https://doi.org/#
If no Author, put the work Title first; but be certain it is not a corporate author.
If no date, use n.d.
Publisher is omitted for periodicals and where it is the same as the Author or Source.
