Dimension X

This log is based upon extensive research both at the Library of Congress as well as
various other sources including interviews with several production personnel from the series.
To the best of my knowledge, it is the most complete log of Dimension X available as of November 19, 2010.

Note: Broadcast dates are based upon NBC log files and does not mean an episode
wasn't broadcast on another day. The show was distributed transcribed to affiliates for most of
its run and individual stations sometimes broadcast it on dates that did not coincide due to conditions at their station.
