<DIV>The use of mixed methods designs for conducting research has become a major trend in social science research. Renowned methodological experts Janice Morse and Linda Niehaus present a guide to intermediate and experienced researchers on the possibilities inherent in mixed method research. They offer the basic principles of conducting this kind of study, then examine a wide variety of design options available to the researcher, including their strengths and weaknesses and when to use them. Providing examples from a variety of disciplines, examining potential threats to validity, and showing the relationship between method and theory, the book will be a valuable addition to the methodologist's library and a useful text in courses in research design.</div>
