Chicago Style Guide, for 17th Edition

Introduction

            The bibliographic entries for magazines are styled nearly identically to journals. The only difference is that the publication date is no longer enclosed in parentheses as it is more common (and more important) than a volume or issue number (if it even exists). As with all citations, enough information should be given so that any interested reader can find the referenced materials. Remember that each element is separated by a period (unless shown otherwise below):

Bibliographic entries of magazines require some or all of the following elements:

1. Full name(s) of authors (Lastname, Firstname. All other authors Firstname Lastname).
2. Title and subtitle of article or column, with all major words capitalized(surrounded by quotation marks).
3. Title of periodical with all major words capitalized (in italicized characters).
4. Issue information if it exists(volume title and/or number), followed by the publication date (month, day, year).
5. Page numbers (where appropriate).
6. URL/DOI (for online publications).

As with all other citations, the publication date of the reference will be placed directly after the title when using Author-Date style.
