What is "The Information?"

For those of you who like intellectual histories, they don't come much grander than James Gleick's new book, which offers up a smorgasbord of thought related to that most central of modern themes, "information." The NY Time's Book Review:

Gleick makes his case in a sweeping survey that covers the five millenniums of humanity’s engagement with information, from the invention of writing in Sumer to the elevation of information to a first principle in the sciences over the last half-century or so.

Despite an argument with Gleick over the extent to which information and meaning are related - "there's no road back from bits to meaning" - the reviewer praises "The Information" for its survey of an idea that has become the essential backdrop to nearly every recent discovery and discussion, from Watson and Crick's double helix to the Libyan revolution.
