Well-known general reference works are typically only cited in notes; they are not given a bibliography entry.
Example 1 – Well-known General Dictionary
N: 1. Oxford English Dictionary, s.v. "Saturnalia, n.," accessed July , 2024, https://www.oed.com/dictionary/saturnalia_n?tab=meaning_and_use#24299989.
Example 2 – Well-known General Encyclopedia
N: 1. Encyclopaedia Britannica Online, Academic ed., s.v. “Arturo Toscanini,” accessed July 1, 2024, https://www.britannica.com/biography/Arturo-Toscanini.
The distinction between general and specialized reference works is not always clear. If a dictionary or encyclopedia focuses on a particular subject or topic, and if the entries within it are substantial and are authored by scholars whose names are provided, it is likely best to use the format shown below.
Example 3 – Specialized Dictionary or Encyclopedia
N: 1. Rajesh Kumar, "Little Ice Age," in Encyclopedia of Snow, Ice and Glaciers, ed. Vijay P. Singh, Pratap Singh, and Umesh K. Haritashya (Springer, 2011), https://link-springer-com.uleth.idm.oclc.org/referenceworkentry/10.1007/978-90-481-2642-2_333.
B: Kumar, Rajesh. "Little Ice Age." In Encyclopedia of Snow, Ice and Glaciers, edited by Vijay P. Singh, Pratap Singh
and Umesh K. Haritashya. Springer, 2011. https://link-springer-com.uleth.idm.oclc.org/referenceworkentry/10.1007/978-90-481-2642-2_333.
If you are consulting a dictionary or encyclopedia in print, see the Manual, 14.130.
Please note that Chicago now omits the place of publication for books published after 1900 (see the Manual, 14.30). For books published before 1900, they recommend using the place of publication instead of the publisher itself, as it is of greater interest (see the Manual, 14.31).
