Publications exist along a broad continuum, with popular magazines being the least scholarly, and scholarly journals being the most scholarly. Occupying a position somewhere in between are trade journals, which exhibit characteristics of both.
Of course, the demarcation between the divisions are not always clear cut, with some popular magazines containing lengthy articles aimed at a highly-educated public, and some scholarly journals featuring primarily short, easy-to-read articles.
