Academic v popular: What is a journal?

A journal (or serial or magazine) is published in a numbered sequence, usually on a regular basis, eg weekly, monthly, bimonthly, quarterly.

Each issue of a journal consists of a number of papers (articles) each by a different author or group of authors; the issues are often combined into volumes.
