Physics 163 - How Things Work

Referencing Web Sites

From the APA & Publication Manual:

If you cite multiple webpages from a website, create a reference for each. To mention a website in general, do not create a reference list entry or an in-text citation. Instead, include the name of the website in the text and provide the URL in parentheses.

For help in determining the author of a webpage or website reference, including how the author can be inferred from context or found on an “about us” or acknowledgments page, see Example 113 below.. Provide the most specific date possible: for example, a year, month, and day; year and month; or year only. When the author name and the site name are the same, omit the site name from the source element. DO not include a retrieval date unless the content is designed to change over time.

Use the template below to construct references for webpages or websites

(Please note that the examples below do not display the double-spacing or hanging indent required in an APA 7 paper.)
