'This book fills an important void in the social network literature by bringing together theory, methodology and history. Its practical and readable style gives clear guidance on how to do social network research and will be invaluable to anyone undertaking a network study' - Martin Everett, Chair of Social Network Analysis, Manchester University 'Christina Prell has produced an excellent and well-crafted introduction to methods of social network analysis. She has succeeded in the difficult task of setting out a clear and accessible statement of core ideas together with a judicious overview of the most advanced recent developments. Her discussion concludes with an introduction to basic software for network analysis that will be much valued by all who are new to the area. The book will become an essential guide to the field for newcomers and seasoned users alike' - John Scott, Professor of Sociology, Plymouth University We live in a world that is paradoxically small and vast: each of us is embedded in local communities and yet we are only a few 'links' away from anyone else in the world.This engaging book represents these interdependencies' positive and negative consequences, their multiple effects and the ways in which a local occurrence in one part of the world can directly affect the rest. Then it demonstrates precisely how these interactions and relationships form. This is a book for the social network novice on learning how to study, think about and analyse social networks; the intermediate user, not yet familiar with some of the newer developments in the field; and the teacher looking for a range of exercises, as well as an up-to-date historical account of the field. It is divided into three sections: 1. Historical & Background Concepts 2. Levels of Analysis 3. Advances, Extensions and Conclusions The book provides a full overview of the field - historical origins, common theoretical perspectives and frameworks; traditional and current analytical procedures and fundamental mathematical equations needed to get a foothold in the field.
