In Expanding Liberties Milton Konvitz presents a careful study of the developments which have taken place since the second World War in certain areas of civil liberties and civil rights. His book is divided into three subdivisions, one concerning First Amendment freedoms, a second dealing with civil rights, and a final one dealing with human rights. It is not by any means a complete catalogue of all the recent innovations in these areas. For example the problems involved in illegal search and seizure, or the area of confession, are left untouched although there have been dramatic developments in these years. However, in the areas he has chosen to explore, Professor Konvitz has made a careful analysis of his subject matter with regard to the historical development of these rights and the underlying political philosophies of the constitution. The extensive documentation and reliance upon quotation makes for demanding reading and recommends the book primarily to the interested student or layman rather than the casual reader.
