The American Jewish Year Book has been a key resource for social scientists exploring comparative and historical data on Jewish population patterns. No less important, the Year Book serves organization leaders and policy makers as the source for valuable data on Jewish communities and as a basis for planning. Serious evidence-based articles regularly appear in the Year Book that focus on analyses and reviews of critical issues facing American Jews and their communities which are indispensable for scholars and community leaders. They have done it again. The American Jewish Year Book has produced yet another edition to add to its distinguished tradition of providing facts, figures and analyses of contemporary life in North America. Its well-researched and easily accessible essays offer the most up to date scrutiny of topics and challenges of importance to American Jewish life; to the American scene of which it is a part and to world Jewry. Whether one is an academic or professional member of the Jewish community (or just an interested reader of all things Jewish), there is not another more impressive and informative reading than the American Jewish Year Book.
