Seminal papers on the Principle of Maximum Entropy by
Edwin T. Jaynes (July 5, 1922  April 30, 1998):

Review, vol. 106, no. 4, pp. 620630; May 15, 1957.

This paper started the use of the Principle of
Maximum Entropy in physics

 The philosophy of assuming maximum uncertainty is discussed in Chapter 3 of

die is in E. T. Jaynes, "Information Theory and Statistical Mechanics," pp. 181218 in

Books
There are many textbooks on thermodynamics and energy conversion.
 R. Silbey and R. Alberty, "Physical Chemistry," Wiley; 2001. These
authors are from MIT. Alberty was formerly Dean of Science, and Silbey
is now Dean of Science. It's amazing that anyone can be a Dean and still
keep up with science.
 Typical excellent book in a traditional style, Mark W. Zemansky, "Heat
and Thermodynamics," McGrawHill Book Company, Inc., New York, NY; Third
Edition, 1951, or earlier editions starting in 1937. This book does not
mention information, and starts with assumed knowledge about temperature,
pressure, and volume. Suitable for advanced undergraduates.
 Introductory book, used for sophomores, covering classical thermodynamics
(no information), H. C. Van Ness, "Understanding Thermodynamics," Dover
Publications, New York, NY; 1969. Succinct and carefully crafted treatment.
 Book covering both equilibrium and irreversible thermodynamics,
Herbert B. Callen, "Thermodynamics," John Wiley and Sons, Inc., New York
NY; 1962.
 Careful treatment of classical thermodynamics (no mention of information)
with emphasis on the mathematical formalism, C. Truesdell, "Rational
Thermodynamics," McGrawHill Book Company, New York, NY; 1969. Suitable
for graduate courses, for those with some prior exposure to thermodynamics.
 Textbook developed at MIT in energy conversion (no thermodynamics),
David C. White and Herbert H. Woodson, "Electromechanical Energy Conversion,"
John Wiley and Sons, Inc., New York, NY; 1959.
 An early textbook to use the Principle of Maximum Entropy as an approach
to thermodynamics is M. Tribus, "Thermostatics and Thermodynamics," D. Van
Nostrand Co, Inc., Princeton, NJ; 1961
