Via 99 entries or "mini-chapters," the SAGE 21st Century Reference Series volumes on political science highlight the most important topics, issues, questions, and debates any student obtaining a degree in this field ought to have mastered for effectiveness in the 21st century. 21st Century Political Science: A Reference Handbook serves as an authoritative reference source that meets students' research needs with more detailed information than encyclopedia entries but not so much jargon, detail, or density as a journal article or a research handbook chapter. An editorial advisory board comprised of eminent scholars from various subfields, many of whom are also award-winning teachers, selected the most important general topics in the discipline. The two volumes are divided into six major parts: 1) General Approaches of Political Science; 2) Comparative Politics; 3) International Relations; 4) Political Science Methodology; 5) Political Thought; and 6) American Politics. A section on identity politics includes chapters on topics such as Race, Ethnicity, and Politics; Gender and Politics; Religion and Politics; and LGBT Issues/ Queer Theory. This two-volume resource makes fairly complex approaches in political science accessible to advanced undergraduate and beginning graduate students.
