Mann's book rewards a careful reader with an exposition of how the organization of libraries and databases serve the needs of the researcher - nothing in a library's organization is arbitrary, and this volume carefully explains how to best use that organization for deep research. He teaches useful, high-level techniques with interesting and memorable examples. This can be useful for an undergraduate research course, but it's entirely indispensable for serious academic work. Anyone starting a graduate or doctoral program should read this, as well as anyone looking for more "tips and tricks."
