Novel by Arthur C. Clarke and Stephen Baxter. The Light of Other Days deals mainly with the sweeping social changes brought by making the ultimate surveilance equipment (the Wormcam) available to anyone and everyone, and also with the changes to the lives of its characters, mainly those involved with the owner of OurWorld, makers of the wormcam, Hiram Patterson.

Features such nifty technology as wormcams and their datapipe ancestors, softscreens, and the Search Engine, which is accessible at any time, in almost any place, and routes information straight to your brain.
