In American Constitutionalism, Third Edition, renowned authors Howard Gillman, Mark A. Graber, and Keith E. Whittington offer an innovative approach to the two-semester Constitutional Law sequence (Volume 1 covers Institutions and Volume II covers Rights and Liberties) that presents the material in a historical organization within each volume, as opposed to the typical issues-based organization. Looking at Supreme Court decisions historically provides an opportunity for instructors to teach–and for students to reflect on–the political factions and climate of the day. The third edition has been updated through the 2021 SCOTUS session, and features updated cases, analysis, illustrations, and figures.
