With more than 600,000 copies now in print, The Craft of Research is the unrivaled resource for researchers at every level, from first-year undergraduates to research reporters at corporations and government offices. Seasoned researchers and educators Wayne C. Booth, Gregory G. Colomb, and Joseph M. Williams present a fundamental and accessible text that explains how to build an argument that engages and persuades readers, how to effectively anticipate and respond to the reservations of readers, and how to find and evaluate sources and integrate them into an argument. The fourth edition has been carefully and respectfully revised by Joseph Bizup and William T. FitzGerald. It retains all the wisdom and sound advice of earlier editions but now reflects the way research and writing practices are taught today, as well as how students find and engage with sources in the digital age, and the extensive bibliography of subject area resources has been thoroughly updated. Throughout, The Craft of Research, Fourth Edition, preserves the amiable tone, the reliable voice, and the sense of directness that have made this book an indispensable guide for anyone undertaking a research project.
