Tips

Authors/Editors

If an encyclopedia or dictionary entry has no author or editor, begin the citation with the title of the specific entry, followed by the year of publication in round brackets.

Titles

Capitalize the first letter of the first word of the title of the entry and the title of the encyclopedia or dictionary. 

Capitalize the first letter of proper names in titles, such as names of places or people. Example: Canada

Publication Information for Online Encyclopedias and Dictonaries 

Some print and electronic content is assigned a unique number called a Digital Object Identifier (DOI). If a DOI is provided for an encyclopedia or dictionary, include it after the name of the encyclopedia or dictionary of the entry and edition as "https://doi.org/xxxxx". 

You do not need to put a period after a DOI.

If you accessed the encyclopedia or dictionary through a website, provide the URL instead.

Retrieval Dates

Do not include a retrieval date unless entries are updated over time and are not archived.

In-Text Citation - No Author

If a dictionary or encyclopedia entry has no author, the in-text citation should include the title of the entry. The title of the entry should be in quotation marks, with each word starting with a capital letter. The title of the entry will be followed by a comma and the year of publication. If you are quoting directly from the entry, you will also add the number of the page where the quote appears.

Example:

Paraphrasing:

("Cat Care," 2019)

Quoting:

("Cat Care," 2019, p. 38)

In-Text Citation - Page Numbers

Page numbers may not be available for an online dictionary or encyclopedia entry. Here are some options if you have no page numbers and you are quoting directly:

If paragraph numbers are given, use that number where you'd normally put the page number with the word "para." in front of it. Example: (Smith, 2018, para. 3). This example refers to the third paragraph in the entry

If you have no paragraph numbers, but the entry has section headings, you can use those. Encyclopedia entries often have section headings. Enter the section heading name, followed by the word "section" and then the number of the paragraph within that section. Example: (Smith, 2018, Climate section, para. 2). This example refers to the second paragraph under the Climate section of the entry.

If you have no paragraph numbers and no headings, count the paragraphs manually and include the paragraph number preceded by "para." If the resouce consists only of a single paragraph, as may be the case for many dictionary entries, skip the page/paragraph/section information and give the author's last name and date only. Example: (Smith, 2018)
