Crossing Borders: International Studies for the 21st Century

Welcome to the SAGE edge site for Crossing Borders, Third Edition.

The SAGE edge site for Crossing Borders by Harry Chernotsky and Heidi Hobbs offers a robust online environment you can access anytime, anywhere, and features an impressive array of free tools and resources to keep you on the cutting edge of your learning experience.


Crossing Borders provides a framework for students built upon an understanding of the many borders that define the international system. Renowned authors Harry I. Chernotsky and Heidi H. Hobbs address many of the different fields that constitute international studies—geography, politics, economics, sociology, and anthropology—and give instructors a starting point from which they can pursue their own disciplinary interests. By integrating research and current examples, the Third Edition encourages students to identify their role in today’s international arena and what it means to be a global citizen. Not only do students develop a better understanding of the world, they also receive advice on how to increase their own global engagement through study abroad, internships, and career options.


We gratefully acknowledge Harry Chernotsky and Heidi Hobbs for writing an excellent text. Special thanks are also due to Alicia Fernandez and Michael Makara for developing the ancillaries on this site.
