Professor Michael Maniates, in a review appearing in the September 2003 issue of the journal Energy Policy, writes:

Dr. Koomey could have written a book for policy elites on the arcane details of energy analysis and policymaking. Instead, with Turning Numbers into Knowledge, he chose to craft a volume that speaks to the neophyte: the beginning citizen-activist, the advanced undergraduate and beginning graduate student, the lay community researcher, the person taking an entry-level job in policymaking and looking to make a difference. Remarkably, the book also has much to say to the accomplished policy practitioner.

By explicating in accessible and challenging detail the nuts and bolts of critical thinking and illustrating the essentials of quantitative analysis, Dr. Koomey has provided a great service. His book deserves to be widely read and shared, especially by those who take seriously the fragile yet critical role of an informed citizenry in increasingly complex democratic societies., the Spanish language media giant, reviewed Turning Numbers into Knowledge in June 2003:

Koomey, un virtuoso del análisis y la investigación, ha creado esta obra única para mostrar como a partir de los números se puede llevar una vida de éxito. Enseña las técnicas para enfrentar y resolver problemas, crear estilos y sistemas de trabajo a base de tablas numéricas y convertir la información en un factor de beneficio en todo momento.

In a review appearing on in November 2002, R. Cooper Richey writes:

Turning Numbers into Knowledge is one of those rare books that is simple in its presentation and quietly leaves a deep understanding of its topic. Chapters read like common-sense and jibe with everyday experience in a satisfying way. Koomey is a masterful analyst who has distilled his years of experience into a well-thought-out, well-written book on the "art of problem solving." Koomey's tone is conversational and succeeds in making a potentially dry topic interesting and relevant through genuine insight, clear prose, and real-world examples.

Beth M. Schlesinger, writing in the May 2002 issue of Mathematics Teacher, the magazine of the National Council of Teachers of Mathematics, had this to say about Turning Numbers into Knowledge:

This book is very well organized and includes an extensive set of suggested readings. It is written in clear language with appropriate exercises and many wonderful cartoons and quotations. It is very readable. I highly recommend it for teachers and advanced students.

In a review of Turning Numbers into Knowledge in the Winter 2002 issue of the journal Issues in Science and Technology Librarianship, Allison V. Level (reference librarian at Colorado State University) said:

Turning Numbers into Knowledge is an engaging and readable book on quantitative problem solving and the process used to transform data or numbers into clear and useful information.

The reader will learn … how to take a critical eye to the analysis presented in reports, newspaper stories, or books. What do the numbers say? What's important? Is the source credible? Does the author of the study have genuine knowledge in the field? Koomey's expertise lends itself to these sections where he gives wonderful examples of what to do, what not to do, and how to question authority. He also tips his hat to librarians and encourages researchers to seek out help from the information professional.

The book is written for broad audience appeal with short clear chapters and lots of visuals including tables, charts, and cartoons ...This book is recommended for all university and public libraries.

In one of their Speed Reviews (February 2002), Soundview Executive Book Summaries describes why they like the book:

Koomey['s] ... guidance is readily available in a user-friendly format that takes readers from examples to points succinctly and clearly. The short chapters keep the ball of information rolling... Each chapter then follows up its lessons with an exercise...By combining this compelling format with strategically placed cartoons and quotations that illustrate his timely topics, Koomey has created a well-conceived, fast-paced book that offers strong advice with expertise and wit.

In its Nov./Dec. 2001 issue (p.64), the Skeptical Inquirer calls Turning Numbers into Knowledge "a lively, well-written, attractively packaged book on the art of critical thinking" and The Midwest Book Review says it's "very highly recommended."

On 29 July 2001, Jonathan Koomey was interviewed by Dr. Moira Gunn of public radio's Tech Nation program. To download the file and listen to that interview using Real Player, click here. It was also reviewed favorably in the April 12-May 20th, 2001 edition of Chance News (an electronic newsletter for statisticians) and in the September 3, 2001 issue of the Fresno-based Business Journal.

Turning Numbers into Knowledge deals with the fundamentals of analysis, research, and problem solving, not with their fashionable technical adornments. It is a tremendous resource for anyone wanting to critically review anything from technical studies to everyday rhetorical argument.

The adjectives that came to my mind as I read Turning Numbers into Knowledge were, ‘Engaging, comprehensive, down-to-Earth, well-researched, well-written, well-planned, well-documented, creative, helpful, entertaining, filled with useful resource material, user-friendly, personal, witty, and wise.’

Whereas I had anticipated a ponderous technical tract, Turning Numbers into Knowledge entertainingly deals with problem solving and analysis in its broadest context, including the often-ignored yet critical human elements. Because of its breadth, I can scarcely think of any scientist, social scientist, student, researcher, writer, or policy analyst who could not benefit from this book. Its lessons are brought home with cleverly chosen anecdotes and lucid examples. The reader is rewarded frequently with wonderful quotations and great cartoons.

What Koomey says about use of the Internet, web sites, and information dissemination over the Internet also has valuable implications for modern administrators, project managers, and executive directors whose organizational management responsibilities increasingly include management and dissemination of information.

As with other classics, I expect Turning Numbers into Knowledge to be in print for a long time and would not be surprised to see students a generation from now relying on a future edition. Jon Koomey is a hard worker, clear thinker, and has produced an extraordinarily useful book that will help the practitioners of science, research, policy analysis, and journalism in the pursuit of truth.”
