From Cosma Shalizi, American Scientist

David Easley and Jon Kleinberg’s Networks, Crowds, and Markets is one of the first textbooks on what could reasonably be called network science—the study of networks of semiautonomous but interdependent units and of the way those networks shape both the behavior of individuals and the large-scale patterns that emerge from small-scale interactions. This is, of course, a very broad description, and it’s not at all obvious that a single book should try to explain, within a common framework, information search on the Web, the spread of epidemic diseases, patterns of scientific collaboration, and much else besides. That these topics are grouped together not by rambling paranoiacs (who find connections everywhere), but by sober, mathematically minded scientists, employing a common and coherent set of concepts, testifies to a remarkable change in perception over the past few decades among scientists and the general educated public: We now see networks everywhere.

Studies dealing with what we now recognize to be social networks go back to the years around 1900, when political economists, social reformers and muckraking journalists began looking at interlocking directorates of corporate boards and other institutions through which the ruling classes (as they were then called) coordinated their actions without actually having an executive committee. People spoke of “social circles.” By the 1950s, sociologists had a notion of social networks, a concept that had a small band of enthusiastic devotees but was an esoteric idea even within mathematical social science. Even 25 years ago, the idea of networks as a form of social organization was reasonably avant-garde. (One can trace some of this evolution in Linton C. Freeman’s 2004 book, The Development of Social Network Analysis, but a proper history of the “network” concept has not yet been written.)

From The Economist

There are few divisions of the book industry with a worse reputation than business publishing. Hundreds if not thousands of business books come out every year, all with glowing press releases and effervescent puffs. Literary editors tend to consign them straight to the bin.

This is understandable. An astonishing number are worthless. Celebrity CEOs blow their trumpets, consultants market miracle cures, self-help gurus promise that you can grow rich by working four hours a week. Wait a few months: the CEOs have been caught with their hands in the till, the miracle cures are poisons, the self-help gurus bankrupt. What remains is a tangle of jargon-ridden prose.

Understandable but wrong. It is silly to dismiss a whole genre just because so many business books are bad. There are some excellent titles in among the dross: CEO biographies that capture something essential about business, useful prescriptions for restoring companies to health, even self-help books that help make sense of the contradictory pressures of modern corporate life. The average employed person in the West spends more waking time in the office than at home, so it makes no sense to be so dismissive of writers who focus on such an important activity.
