Evaluating Periodical Articles Evaluate periodical articles before you decide to use them in your research. As you might have thought by now, your reading of an article's bias may in turn be influenced by your own points of views and values. Articles can cover a wide range of topic, depending on the subject of the index itself. Each volume of an index covers one year's worth of articles. Most databases cover a range of years.
Periodical databases provide citations and full-text for newspaper, magazine and journal articles.
The Nursing Database gives only citations for articles about nursing and allied health sciences. If you are using a periodical index, or a citation only periodical database, you will need to locate the journal articles within your library, or order them on Inter-Library loan.
