Authors are authorities in their fields. Authors cite their sources in footnotes, endnotes, and bibliographies. Individual issues have little or no advertising. Articles must go through a peer-review process. Articles are usually reports on scholarly research.
Most illustrations are charts and graphs.
Articles use jargon of the discipline. Authors are magazine staff members or free lance writers. Authors may mention sources, but rarely cite them formally in notes or bibliographies. Individual issues contain numerous advertisements. There is no peer review process.
