The quality of your final product, i.e. your essay, research paper or presentation, depends on the quality of the resources used for your research. Although the materials available from an academic library undergo an evaluation process before and after being purchased, you should evaluate your sources in relation to your particular approach to a topic.
You can begin your evaluation by examining the bibliographic citation that appears in the library catalog or index. There are three main components that are characteristic of bibliographic citations: author, title, publication information. This information can help you determine the usefulness of the source. The source should be reliable, relevant, respected, and current.
