Q: I cannot find anything in the AMA Manual of Style about how to cite an article in a magazine. Please help.

A: You are correct that we do not address citations to magazines, primarily because the material we focus on is more scholarly. However, you could extrapolate from the information on how to cite a journal article (see section 3.11). Here is an example of citation of a magazine article:

Angell R. This old man: life in the nineties. New Yorker. February 17&24, 2014:60-65.

You’ll notice that although we prefer giving the year;volume number(issue number):inclusive pages in our citations to journal articles, some magazines do not use volume and issue numbers but instead rely on the issue date. This seems to be true of the New Yorker, and this article was in a double issue, so you’ll see that I have suggested using issue date:inclusive page numbers.

Q: What is the best way to send a question to you regarding the content of the style manual?

A: You may write to the style manual at stylemanual@jamanetwork.org.

Q: For package insert references, many times the manufacturer and marketing company are the same. However, if they are not, which company should be listed in the reference citation?

A: It might be helpful in the case of a manufacturer and a marketer to list both. In this case, you could separate them by a semicolon:

Onglyza [package insert]. Princeton, NJ: Bristol-Myers Squibb Co; Wilmington, DE: AstraZeneca Pharmaceuticals LP; July 2009.—Cheryl Iverson, MA
