Annotated Bibliography
Primary sources both seen and unseen noted here with enough information to state why they might be of use. They should also be categorized as to type of source (document, data, artifact, oral) with critical analysis as to fact vs. supposition and objectivity vs. bias of those sources seen for this study. Chicago Method style.
Secondary and other sources both seen and unseen noted here with enough information to state why they might be of use, and how they agree or disagree with your thesis and how you can address this. Remember you have to state what you would add that has not been stated before unless you are looking at it with a new different method (such as quantification) and this will be discussed in the next session. Chicago Method style.
