AMA 11th Referencing Guide

Referencing guide for the 11th Edition of AMA Style

No volume or issue numbers

You should always try to find volume and issue number for journal articles. However, some journals genuinely don’t have volume or issue numbers.  If you have tried to find the information, and you simply cannot, then you skip that part of the pattern.

The full pattern (year;volume(issue):pages) looks like this:  2008;178(1):9-16.

If the journal did not have issue numbers then it will be 2008;178:9-16.

A missing volume number would look like this: 2008;(1):9-16.

And if both volume and issue numbers are missing it will look like this: 2008:9-16.

Note that you still use a colon before the page numbers.
