APA Referencing Guide: Periodicals

Periodicals  - Introduction

A periodical publication will appear in a new edition on a regular basis. For example, weekly, monthly or quarterly.

Periodic literature includes:

• Journals
• Magazines
• Newspapers
• Newsletters
• Blog Post

Periodicals are typically published and referenced by volume and issue number: 

• Volume typically refers to the number of years that the publication has been circulated,
• The Issue Number refers to how many times the periodical has been published during the year.

So, for example, the March publication of a monthly journal that is currently in its fifth year of circulation will have Volume = 5,  Issue Number = 3.
