Please include a minimum of six sources total (this should include both primary and secondary sources, but at least three of these should be secondary sources), which you have read as part of your preparation for your final paper. Please remember to include your chosen topic at the top of your annotated bibliography along with your name. The entries of your annotated bibliography should be divided into primary and secondary sources and should be listed in alphabetical order in the same way as a normal bibliography or list of works cited. You may use the citation style of your choice for the form the entries take but all entries should be consistent within this style. Please put which style you have chosen to use at the top of the assignment. Each entry should be followed with a few brief sentences describing what the main point the source is trying to communicate is and how this is reinforced within the source, i.e. what the main argument is and how the author supports it if it is a secondary source -or- what the main narrative is if it is a primary source. In addition to this, for each entry you should include at least one sentence describing why this source will be useful to your final paper and how you intend to use it in this paper.
