Perhaps because what constitutes an adequate methodology for writing film history remains unsettled, these essays by 24 writers have varying success in explaining the development of film in the more than 30 countries treated here. The least successful and least interesting entries merely arrange film titles by director, theme, and chronology. The more thoughtful sectionsparticularly those on Canadian, Czechoslovakian, and French filmcombine economic and social data to reveal the forces and ideas that have shaped a specific nation's output during these years. Despite the unevenness, the collection offers a handy one-volume reference that should be useful to film libraries. Marshall Deutelbaum, English Dept., Purdue Univ., W. Lafayette, Ind.
