In this guide to the literature on human migration, J.J. Mangalam indexes over 2,000 titles that appeared in English from 1955 through 1962. An important feature of this work is the annotation of nearly 400 major articles on migration. These annotations provide information on the main focus of the study, the hypotheses tested, and any special measuring devices employed. The conclusions are also given, using the authors' words whenever possible. To facilitate the use of this guide the author has compiled an index that lists not only the subjects treated but also the major variables used in each abstracted study; thus the researcher who is interested in the use of certain variables can easily refer to the previous investigation of the influence of these factors upon migration. In a comprehensive introduction, Mangalam surveys the current state of studies of human migration and suggests a theoretical framework by which the vast amount of existing facts from different migration studies can be integrated and given meaning.
