Tarleton State University Libraries Unit 3 EVALUATING RESEARCH MATERIALS   Once you have located research materials, you must now evaluate them to see if they •  fit your information need, •  provide appropriate types of information, and •  offer information that fits both the purpose of your project and your intended reader's expectations. Because evaluation is such an important part of the research process, Unit 8 presents an in-depth discussion of evaluation and offers criteria and strategies to use when evaluating •  books (print and online), •  articles in periodicals (print and online), and •  Internet sites.     Keeping a Research Log Learning Activities    Library Orientation Site Index Updated 7/2004
