Since the publication of the first edition of Content Analysis: An Introduction to Its Methodology, the textual fabric in which contemporary society functions has undergone a radical transformation -- namely, the ongoing information revolution. Two decades ago, content analysis was largely known in journalism and communication research, and, to a lesser extent, in the social and psychological sciences. Today, content analysis has become an efficient alternative to public opinion research -- a method of tracking markets, political leanings, and emerging ideas, a way to settle legal disputes, and an approach to explore individual human minds. The Second Edition of Content Analysis is a definitive sourcebook of the history and core principles of content analysis as well as an essential resource for present and future studies. The book introduces readers to ways of analyzing meaningful matter such as texts, images, voices -- that is, data whose physical manifestations are secondary to the meanings that a particular population of people brings to them.Organized into three parts, the book examines the conceptual and methodological aspects of content analysis and also traces several paths through content analysis protocols. The author has completely revised and updated the Second Edition, integrating new information on computer-aided text analysis. The book also includes a practical guide that incorporates experiences in teaching and how to advise academic and commercial researchers. In addition, Krippendorff clarifies the epistemology and logic of content analysis as well as the methods for achieving its aims. Author Klaus Krippendorff discusses three distinguishing characteristics of contemporary content analysis: that it is fundamentally empirically grounded, exploratory in process, and predictive or inferential in intent; that it transcends traditional notions of symbols, contents, and intents; and that it has been forced to develop a methodology of its own, one that enables researchers to plan, execute, communicate, reproduce, and critically evaluate an analysis independent of the desirability of its results.Intended as a textbook for advanced undergraduate and graduate students across the social sciences, Content Analysis, Second Edition will also be a valuable resource for practitioners in a variety of disciplines.

Klaus Krippendorff (PhD in Communication, University of Illinois, Urbana, 1967) is Professor of Communication and Gregory Bateson Term Professor for Cybernetics, Language, and Culture at the University of Pennsylvania's Annenberg School for Communication. Besides numerous publications in journals of communication, sociological methodology, cybernetics, and system theory, he authored Information Theory, Structural Models for Qualitative Data, a Dictionary of Cybernetics, edited Communication and Control in Society, and coedited The Analysis of Communication Content and Developments and Scientific Theories and Computer Techniques.

Besides supporting various initiatives to develop content analysis techniques and continuing work on reliability measurement, Klaus Krippendorff’s current interest is fourfold: With epistemology in mind, he inquires into how language brings forth reality. As a critical scholar, he explores the conditions of entrapment and liberation. As a second-order cybernetician, he plays with recursive constructions of self and others in conversations; and as designer, he attempts to move the meaning and human use of technological artifacts into the center of design considerations, causing a redesign of design – all of them exciting projects.
