Journal articles are shorter than books and written about very specific topics.
A journal is a collection of articles (like a magazine) that is published regularly throughout the year. Journals present the most recent research, and journal articles are written by experts, for experts. They may be published in print or online formats, or both.
The front cover of a sample academic journal (PORTAL: Journal of Multidisciplinary International Studies). Note that it includes a year, as well as "Vol." (for "Volume") and "No." (for "Number"). Because journals are published regularly, this information identifies different issues (like month and year on a popular magazine).
A sample table of contents from the same academic journal, listing the articles that appear in this issue. (Note: When accessing journals online, articles are usually available as separate PDF documents.)
