The article presents information related to the special issue on transportation proceedings of the Institute of Electrical and Electronics Engineers. The concept of the goals of the issue was outlined by the editorial committee of the institute. The issue is planned to be more than a collection of papers on random topics in transportation. It will serve as a coherent introduction to the subject for most of its engineering readers. Three major areas will be considered. The purpose of this issue will be to acquaint today's engineer with what surely will be one of the most rapidly growing areas of research and development in the coming decade. The issue will limit itself to terrestrial, i.e., nonspace travel, but within this restriction will be as broad as possible. The papers included in this issue focus on different and important topics. Some of the papers report on an area far afield from most of the readers. They cite new areas of research and development which promise greatly increased cost effectiveness for this most ancient form of transportation.

The article focuses on the book "Social Mobility in the Caste System in India. An Interdisciplinary Symposium," edited by James Silverberg. In the book, author aim to further an understanding of the nature, extent and significance of social mobility in a caste system and to uncover the mechanisms and determinants involved. The book offers a review of the sociological concern with social mobility in the caste system as a general set of processes. A set of four papers presents and evaluates evidence concerning social mobility, based in three instances on recent first-hand observations and in the fourth on data extracted from the medieval period by the techniques of the historian. The first two papers are the products of anthropological field research in rural communities: a South Indian case by researcher Edward B. Harper, who combines ethnographic and ethnohistorical methods; a North Indian case by researcher William L. Rowe, who gathered his ethnographic data not only among the Caubans of the village in which he lived but also from their city-dwelling caste fellows, the politicians and other professionals whom he interviewed in Bombay, India and several urban centres of North India.

The article focuses on the book "Developments in Educational Testing," edited by Karlheinz Ingenkamp. The book reproduces in English 79 papers on educational testing given at an international conference held in Berlin from 16-24 May, 1967. The authors are experts in measurement from all over the world, and they have made important contributions in the field of testing. The contents include testing throughout the world, educational objectives of testing and varying types of tests for the assessment of scholastic achievement.
