Download and use the Research Journal (above) to help plan, organize, track and revise your research. You may need to download the newest version to Adobe Reader to use this document.
Here are some resources beyond the library (often organized by different communities) that may help you in your search for additional information. Often material that has a different scope, focus or audience than traditional scholarly information can add complexity, interest or local relevance to your topic.
Apply the same scrutiny to the material you find through these sites that you would to any other information. Use the questions on the back of your Research Journal to evaluate the information.
