The International Encyclopedia of Political Science provides a definitive, comprehensive picture of all aspects of political life, recognizing the theoretical and cultural pluralism of our approaches and including findings from the far corners of the world. The eight volumes cover every field of politics, from political theory and methodology to political sociology, comparative politics, public policies, and international relations.

This major new edition of The Oxford Companion to Politics of the World reflects the changing world with a reassessment of many of the core themes of the previous edition, and new articles on the people, concepts, and events that have shaped the world since 1993.

The Companion focuses on the major theories, concepts, and conclusions that define the field, analyzing the similarities and differences between political units. Additionally, the Companion outlines those comparativists who have influenced the field in significant ways, and politicians whose administrations have shaped the evaluation of contrasting governments. Drawing on the depth and breadth of content from the Oxford Companion to Politics of the World, the Oxford Companion to Comparative Politics contains nearly 200 revised and updated articles from this foundational set in addition to over 100 new entries, which thoroughly examine the field.

The Political Handbook of the World 2024–2025 is an authoritative and comprehensive reference guide available for understanding the political landscape of every nation and territory across the globe.
