Popular Magazines/Newspapers:
- glossy, pretty pages with lots of advertisements and pictures
- written by hired reporters for a general audience
- short, easily read articles
Scholarly Journals:
- somewhat dull looking - very few pictures or advertisements
- written by experts in the field and reviewed by other scholars before publication
- long articles with citations and bibliographies at the end
And about literature reviews!
