How to Cite an Encyclopedia in APA Style

Encyclopedias are comprehensive sources often used in academic research. Citing encyclopedias in APA style varies depending on whether they are print or online, and if they have individual authors for entries. Key elements include the author (if available), publication date, entry title, encyclopedia name, and publisher. For online encyclopedias, include the retrieval date and URL. These details apply to both in-text citations and reference list entries.

Types of Encyclopedias: Print vs. Online

Encyclopedias are available in print and online formats. Print encyclopedias are traditional hardcopy volumes often found in libraries, usually consisting of several volumes covering many topics. Online encyclopedias, like Wikipedia and Britannica Online, are digital and accessible via the Internet. Each format has specific citation requirements that must be followed for proper attribution.

When to Cite an Encyclopedia

Encyclopedias are great for general overviews or background information. They’re useful for defining terms, summarizing historical events, and explaining complex concepts concisely. However, primary sources or scholarly articles are preferred for detailed and specific information.

Basic Format for Citing an Encyclopedia in APA

You must include several key elements to cite an encyclopedia in APA style. These elements ensure your citation is complete and allow readers to locate the original source.

Authoritative Elements

An encyclopedia citation should include the author’s name, the publication year, the title of the entry, the title of the encyclopedia, the volume and page numbers (for print), and the URL or DOI (for online). These elements ensure a complete reference, guiding the reader to the source.

General Structure for Print and Online Encyclopedias

For print encyclopedias, the structure typically looks like this:

Author Last Name, First Initial. (Year). Title of entry. In Editor’s First Initial. Last Name (Ed.), Title of Encyclopedia (Vol. number, pp. pages). Publisher.

For online encyclopedias, it usually appears as:

Author Last Name, First Initial. (Year). Title of entry. In Title of Encyclopedia. Retrieved from URL

Special Cases and Variations

Example:

Multiple Authors

Edited Volumes

For entries in edited encyclopedias, include the editor’s name followed by the abbreviation “Ed.” in parentheses.
