Heated bed general discussion and applications
Traumflug's page on theory behind heated bed design, with formulae
The discussion on using metal surface for heated bed gave me the idea of using a thin layer of a good thermal conductor like copper or aluminum (expand too much) under glass to improve heat distribution.
