This library guide is written for the purpose of assisting the students in Micro 450 with literature searches. There are suggestions and tips on not only how to find literature, but also important concepts in understanding literature, such as primary versus secondary sources of information. Perhaps of most importance in this library guide is a link to useful databases that will prove to be of great importance when seeking biological literature. As advanced undergraduate students, you should understand by now the importance of knowing how to find biological information. This is a skill which will be, for most of you, used for your entire professional life, and searching databases for information is not merely a student activity.
