For research projects you will be using two basic types of information: Primary and Secondary. Your instructor will usually tell you what types of information he or she expects you to use for your research. What's the difference between these types?
Primary sources are original materials that were created firsthand; they have not been run through the filter of interpretation.
Because primary sources are the documents or artifacts closest to the topic of investigation, they are a great way to gain insight into and an understanding of an event or topic. Often they are created during the time period that is being studied but they can also be produced later by eyewitnesses or participants.
You may find primary sources in their original format (usually in an archive) or reproduced in a variety of ways: books, microfilm, digital, etc.

Unless otherwise instructed by your teacher, you'll probably want to use a variety sources to help you gain a complete understanding of your topic. Sources of information generally fall within three categories.These categories are Popular, Substantive, and Scholarly (or Peer Reviewed). To use them skillfully you need to be able to identify them and understand their differences.
