From July 25-August 6, 1966 a Summer School on Local Fields was held in Driebergen (the Netherlands), organized by the Netherlands Universities Foundation for International Cooperation (NUFFIC) with financial support from NATO. The scientific organizing Committl!e consisted ofF. VANDER BLIJ, A.H.M. LEVELT, A.F. MaNNA, J.P. MuRRE and T.A. SPRINGER. The Summer School was attended by approximately 80 mathematicians from various countries. The contributions collected in the present book are all based on the talks given at the Summer School. It is hoped that the book will serve the same purpose as the Summer School: to provide an introduction to current research in Local Fields and related topics. July 1967 T.A.

First multi-year cumulation covers six years: 1965-70.

The ten essays in this volume represent state-of-the-art surveys of ten singular episodes in U.S. interaction with the Third World since 1945. Each author seeks to present a unique approach to a specific topic within U.S. -- Third World relations. The essays cover the globe and include studies of the Middle East, Latin America, Africa, and Asia. They make use of a variety of source material and employ a wide range of analytical devices, such as the national security paradigm, the idea of economic development, and culture. The essays present a multihued portrait of the different ways policy makers in the United States dealt with Third World problems. The essays make clear the multitude of considerations that affected policy making; the many different actors, both official and nonofficial, who came to influence the policy-making process; and the possibilities for future research into U.S. relations with the nations of the Third World. They are designed not only to present the current state of the literature but also to suggest some avenues for future research.
