Your task is to propose a thesis on a topic and to support that thesis with ideas and information gleaned from your research sources. In other words, you will construct a logical, cohesive patchwork of ideas including those of authors whose work you read/view/hear along with your own understanding and interpretation of the topic.
Identify at least the minimum number of sources required for the assignment, preferably 1-2 more than the minimum to afford you some valuable power of choice.
Evaluate the relative usefulness of the potential sources.... usefulness to your purpose. You are tasked with developing and supporting a thesis in your essay or paper. Each source you select must contribute to the whole in a significant fashion.
Consider using a chart to help you keep track of the ways each source is unique and useful.
