Book excerpt: The U.S. Congress can be traced to the founding and the debates in Philadelphia in the summer of 1787, but to suggest that the Congress in the first decade of the 21st century is the same Congress that was created over 220 years ago would be wildly misleading. The entries in this volume will elaborate on the original compromises and the ensuing evolution of legislative practice and review how Congress has developed through several distinctive eras. This second edition of Historical Dictionary the U.S. Congress contains a chronology, an introduction, and an extensive bibliography. The dictionary section has over 500 cross-referenced entries on the key concepts, terms, labels, and individuals central to identifying and comprehending the key role Congress plays in the history of the U.S. This book is an excellent resource for students, researchers, and anyone wanting to know more about the U.S. Congress.
