The only book that develops constitutional law in the comprehensive sense, American Constitutional Law not only contains the results of court decisions but also highlights the efforts of legislatures, executives, the states, and the general public. Available in two formats — a single, hardback volume or two paperback volumes — it covers all new developments in case law, congressional statutes, presidential policies, and initiatives undertaken by states under their own constitutions.

Most constitutional law books focus only on case law and judicial pronouncements, but American Constitutional Law illustrates how both judicial and non-judicial forces shape constitutional law. Compared to other texts, this book offers more citations to earlier decisions, allowing the reader to research areas in greater depth and better understand the process of trial and error used to shape constitutional principles. A broad range of cases (not just landmark cases) is combined with nonjudicial contributions. Fisher and Adler also cover state involvement in constitutional law by offering examples of how states, by interpreting their own constitutions, may depart from Supreme Court doctrines.  Readings include not only court cases, but presidential statements and congressional debates.
