The working bibliography (and the bibliography of the final paper as submitted) should contain at least 10 entries, at least half of which are from scholarly sources (academic journals and scholarly books).  A good place to start looking for relevant articles in academic journals is in online social science indexes, such as Public Affairs Information Service, International Political Science Abstracts, and the Social Sciences Citation Index.  Research strategies will be discussed in more detail in class.  See as well the statement on research sources.
