FAQ: How do I cite a resource with no date in Chicago Style?

Generally speaking, if you cannot identify the publication date, use the abbreviation n.d. for “no date.” Here are examples of how it works in the Chicago citation style:

Chicago Style

When the publication date of a printed work cannot be ascertained, the abbreviation n.d. takes the place of the year in the publication details. A guessed-at date may either be substituted (in brackets) or added. The rest of the citation will follow the format of the source (book, journal, website, other medium).
