[A] hell of a book

It's a powerful idea: from org charts to science, from music to retail theory, from government to education, every field of human endeavor is tinged with hierarchy, and every hierarchy is under assault from the Internet. One impact of this change is that it reveals the biases lurking underneath the editorial carvery of our systems. From the Dewey Decimal system's laughable clunkers (mentalist bunkum gets its own category, but Islam has to share a decimal with a couple competing "Eastern" faiths) to the Britannica's paring away at "old" biographies to make way for the new, Weinberger makes a compelling case for a new kind of knowledge that more faithfully represents the messy, glorious hairball of the real world.
