APA Citation Guide (7th Edition): Encyclopedias & Dictionaries (Reference Works)

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

Place of Publication

For cities in the US and Canada list the city name and the province or state code. For other countries, list the city name and the country. Examples: Toronto, ON ; Tokyo, Japan

Publication Information for Online Encyclopedias and Dictionaries

Don't include the place of publication or a publisher for an online encyclopedia or dictionary.

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

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," 2011)

Quoting:

("Cat Care," 2011, 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, 2012, 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, 2012, 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, 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, 2012)

Note: All citations should be double spaced and have a hanging indent in a Reference List.

A "hanging indent" means that each subsequent line after the first line of your citation should be indented by 0.5 inches.

Title of entry. (n.d.). In Wikipedia. Retrieved Month Day, Year that website was viewed, from URL for entry

Note: According to APA, n.d. is used instead of a date of publication as the date is difficult to determine. Include the date you viewed the website as the content is likely to change over time.

Wikipedia may not be considered an acceptable source for a college or university assignment. Be sure to evaluate the content carefully and check your assignment.
