Note the author of the article in the periodical. First, write the author's last name; then, write a comma; then, after a space, write the author's first name or first initial.
Write the title of the article. You can put quotation marks around the title or leave it as it is.
Write the name of the periodical, using italics.
Specify the volume number of the periodical. If there is also an issue number, write that too.
Note the month and year in which the periodical was published. If it is a newspaper, or if it is published more than once a month, then you should also note the specific day.
Write the article's page range (the first and last pages of the article within the periodical). Separate the numbers with a hyphen or n-dash.
