Article Databases mostly contain articles from periodicals, including:
Journal Articles, which cover research and practice in a particular field or discipline. These articles are written by experts in the field and are a VERY HIGH QUALITY SOURCE. You can limit your search to just journal articles by checking the scholarly or peer-reviewed journal box on the search screen.
Magazine and Newspaper Articles, which are geared more to the general public--not as high quality as journal articles, but may be appropriate depending on your topic. Use the Source Evalauation Rubric under the Evaluating Sources tab to evaluate these types of articles.
Some databases, especially those geared to a particular topic such as Literary Reference Center, contain periodical articles as well as articles from reference books.
If your research assignment requires you to write about literary criticism or literary themes, the following databases are a good place to start.
