Identifying the type of source you are using can help in evaluating the source.
With any research project you should consult and compare multiple sources. One reason to do this is to compare the information you find. Another reason is to overcome the shortcomings of a source by using another source type. For example, you may find a newspaper article which provides relevant and timely facts on your topic. However, the newspaper article is short and offers limited information and no analysis. Using a more in-depth source like a book or journal article will help you balance your research.
