How do I format sources with 2 or more authors in the bibliography and footnotes?

How do I format sources with 2 or more authors in the bibliography and footnotes?

Two or more authors of the same work are listed in the order in which they appear with the source. In a bibliography, only the first author's name is inverted (the remaining authors are not inverted). 

Bibliography Example of 2 authors:
Levitt, Steven D., and Stephen J. Dubner. Freakonomics: A Rogue Economist Explores the Hidden Side of Everything. New York: William Morrow, 2005.

Footnote Example: 

Steven d. Levitt and Stephen J. Dubner, Freakonomics: A Rogue Economist Explores the Hidden Side of Everything (New York: William Morrow, 2005), 20-21. 

Shortened Form of Footnote (after full, initial footnote is given): 

Levitt and Dubner, 20-21.

Bibliography Example of 3 authors:

Smith, John, William Harriet, and David Thompson. The Battle of Britain. New York: ABC Publishing, 1995.

Footnote Example:
John Smith, William Harriet, and David Thompson, The Battle of Britain (New York: ABC Publishing, 1995), 130.

Shortened Form of Footnote( after full, initial footnote is given): 
Smith, Harriet, and Thompson, 130.

For a source by four or more authors, you would still list all the author's names in the bibliography. However, in the footnotes, you would use et al. : 

Bibliography Example: 

Titus, Craig, Paul Vitz, William Nordling, Matthew McWhorter, and Christopher Gross. "Fulfilled in Virtue." In A Catholic Christian meta-model of the person: Integration with psychology and mental health practice, edited by Paul Vitz, William Nordling, and Craig Titus, 249-305. Sterling VA: Divine Mercy University Press, 2020. 

Footnote Example: 

Craig Titus et al., "Fulfilled in Virtue," in A Catholic Christian meta-model of the person: Integration with psychology and mental health practice, ed. Paul Vitz, William Nordling, and Craig Titus (Sterling, VA: Divine Mercy University Press, 2020), 249.

Shortened Form of Footnote (after full, initial footnote is given): 

Titus et al., "Fulfilled in Virtue," 249.

For online sources that do have page numbers, provide the title of the webpage after the author for the shortened footnote (if no specified author, the website name): 

Smith et al., "The War of 1812."
EWTN, "God and His Providence."
