  Errata for the printed edition.
• Entropy and Information Theory, revised 27 January 2007.
• Conditional Rate Distortion Theory, Scanned copy of Information Systems Laboratory Technical Report 6502-2, October 1972, an early work on conditional rate distortion functions and related theory. The report provided supporting details for published papers relevant to the topic, specifically
  ``A new class of lower bounds to information rates of stationary sources via conditional rate-distortion functions,'' R.M. Gray, IEEE Trans. on Info. Theory, Vol. IT-19, No. 4, pp. 480-489, July 1973.

• Amy Heard: Letters from the Gilded Age, revised September 2005.
• Max & Max, Revised July 2005.
• The Salem Houses of William ``Old Billy'' Gray, a note on the houses owned by the Salem merchant along with photos from the Essex Institute (now part of the Peabody Museum) of his best known house, which later became the Essex House until it was torn down to make room for the East India Mall. Be warned this is a 13M file because of the high resolution images.

• Robert M. Gray, Toeplitz and Circulant Matrices: A Review, Now Publishers, Norwell, Massachusetts. This paperback book is available at a 35% discount from Now Publishers by entering the promotional code CITMC06 on the order form .
  You will then pay only $28.00 including postage.
  
• Robert M. Gray and Lee D. Davisson, Introduction to Statistical Signal Processing, Cambridge University Press, December 2004, Cambridge, UK. Cambridge did a very nice job of producing a good looking book for only $70. Much nicer than dealing with printing and managing almost 500 pages from the free version! Solutions to the majority of the problems in the book are available for instructors from Cambridge University Press.
