That's the history, and it is told elegantly by Gleick, helped along by a patchwork of entertaining anecdotes. However, The Information loses its way when it moves into the second half of the 20th century, and into theoretical territory. A hectic journey through quantum physics, randomness, Alan Turing's proof of uncomputability and the question of whether information is finite or infinite leaves one swamped, and Gleick's usual ability to elucidate the most complex ideas seems to have escaped him here.
