"Absolutely groundbreaking: The first fullscale, data driven undertaking to weigh the historical and cultural impact of persons. This work injects a much needed dose of quantitative rigor into the field of history itself. How do the greatest legacies of yesteryear stack up, not only against one another, but against the power of today's celebrity royalty? This thorough treatment illuminates, validates, and even augments history as a discipline."

"Skiena and Ward provide a numerical ranking for the every Wikipedia resident who's ever lived. What a great idea! This book is a guaranteed argument-starter. I found something to argue with on nearly every page.

-- Andrew Gelman, author of Red State, Blue State, Rich State, Poor State: Why Americans Vote the Way They Do"

"Now comes a whole new approach. In Who's Bigger: Where Historical Figures Really Rank, Steven Skiena, a professor of computer science at Stony Brook University, and Charles Ward, an engineer at Google, mine Wikipedia data in order to take a quantitative stab at who stands where in the long march of human accomplishment."

-- from The most important people who ever lived by Kevin Hartnett, Boston Globe, November 29, 2013.

"All this is a lot of fun, and it must be acknowledged that the authors enthusiasm and sense of play are infectious. But there is an obvious question, and it has to do with what exactly Skiena and Ward are measuring. For all their creativity, diligence, intelligence, and good nature, Skiena and Ward have produced a pretty wacky book..."

-- Cass Sunstein, The New Republic, December 3, 2013.

"I confess to simply liking the book. I still do not care about the great order of things, nonetheless, I very much appreciate a huge amount of fascinating detail that the book makes available at one's finger tips, and the orderly manner in which it does that."

-- Alexander Bogomolny, Mathematics Association of America (MAA) Reviews, December 11, 2013.

"This is all fun: reputational face-offs are great entertainment...More seriously, historians will put quantitative analysis to good use and their model may help historiographers grapple with Wikipedia."

-- Jonathon Keats, New Scientist December 30, 2013.

"Who's Bigger? is just a parlor game, wrapped in big words and complext formulae."

-- Gerhard De Groot, The Times of London December 28, 2013.

"... a fascinating, though useless, project, very well executed."
