How to reference a Journal Article using the Chicago Manual of Style
The most basic entry for a journal article consists of the author name(s), article title, journal name, volume number, year published, and page numbers.
Last Name, First Name. “Article Title.” Journal Name Volume Number (Year Published): Page Numbers.
Smith, John. “Studies in pop rocks and Coke.” Weird Science 12 (2009): 78-93.
The first author’s name should be reversed, with a comma being placed after the last name and a period after the first name (or any middle name). The name should not be abbreviated and should be written exactly as it appears in the newspaper. Titles and affiliations associated with the author should be omitted. A suffix, such as a roman numeral or Jr./Sr. should appear after the author’s given name, preceded by a comma.
For an article written by two or more authors, list them in order as they appear in the journal. Only the first author’s name should be reversed, while the others are written in normal order. Separate author names with a comma.
Smith, John, and Jane Doe. “Studies in pop rocks and Coke.” Weird Science 12 (2009): 78-93.
The full article title, which is followed by a period, should be placed within quotation marks. Place the period within the quotation marks. Although Chicago traditionally uses the headline style of capitalizing the first letter of each word in the title, sentence style is also acceptable. Be consistent in your bibliography in using either style.
The article title is followed by the name of the journal, which is italicized. Omit any introductory articles (e.g. A, An, The) from the journal name. Journal names are usually given in full, since it is not incorrect to spell out a journal name. You can abbreviate a journal name if you wish, except if it consists of one word. It is common to abbreviate journal names from scientific works (e.g. Comp Tech Evol).
Include the volume number after the journal name. If an issue number is available, include it after the volume number and before the year published. Precede the issue number with a comma and the text “no.”.

Put the year of publication in parentheses. Afterwards, include a colon, the page numbers the article appears on, and a period. You may include the month or season in parentheses before the year, although it is not necessary if you include an issue number.

If the article was published online, include the web address of the article, and then place the word “accessed”, along with the date on which you accessed the website (written in the format of “month day, year”) in parentheses. Conclude the citation with a period after the parentheses. For an article found in a database, cite it the same way you would an article published online: place the database URL in place of the website URL and cite the date on which you accessed the article.
