I am just finishing The Innovators by Walter Isaacson (the guy who also did Jobs' biography) and it did a good job at tracing the threads of theoretical information management systems through to their practical manifestation via the invention of the web by Berners-Lee. It's a decent read and I'd recommend it if you have an interest in the history of computing as a whole and how the various ideas and concepts that came to shape how computers exist today were first born then later realised.
