Reddit mentions of How the World Was One

Not sure what else you'd like to know, but here are some links:

1. An old but colorful Wired travelogue by Neal Stephenson
   
   
2. A digital exhibition from the Smithsonian, a little hokey but lots of rich descriptions
   
   It is certainly one of the more thrilling stories of 19th-century Victorian engineering, full of ups, downs, and repeated failures; it even features Lord Kelvin (as plain old William Thomson) in a starring role. Arthur C. Clarke tells the tale fairly well in How the World Was One.
