Thermodynamics publications
The following are significant thermodynamics publications, connected or related significantly to human activity, with notable citation counts, albeit ones that do not make direct hypotheses concerning human existence:

#	Thermodynamics Publication	Significance	Authors(s)		Cited by (2010)
	“Principles that Govern the Folding of Protein Chains.”	Proved the thermodynamic hypothesis.		Christian Anfinsen	3156
	Scientific Papers of J. Willard Gibbs, Vol. 1, Thermodynamics (1876)			Willard Gibbs	438
	Thermodynamics and the Free Energy of Chemical Substances (1923)			Gilbert Lewis and Merle Randall	353
	The Mechanical Theory of Heat (1879)			Rudolf Clausius	50

Discussion
The following section discusses individual books whose notability is not recognized by pure citation count. In 1967, American physical chemists Gilbert Lewis and Merle Randall's 1923 Thermodynamics and the Free Energy of Chemical Substances had come to be known as "the world's most quoted scientific book". [1] In circa 2005, independent of the previous quote, the same book was found to be the most cited reference in the reference sections to American chemical engineer Libb Thims' thermodynamics book collection, consisting of over 240 thermodynamics books. Austrian physicist Erwin Schrodinger's 1944 booklet What is Life?, written for the layperson, is likely one of the most-cited books, on the subject of life and entropy, outside of the thermodynamics community.

Of note, the simplified 1969, 102-page, booklet Understanding Thermodynamics, by American chemical engineer Hendrick Van Ness, based on 1968 lectures to sophomore engineering students at the Rensselaer Polytechnic Institute during the spring term, is the highest ranking Amazon.com book on thermodynamics. [3] In addition, Van Ness’, seventh edition, 2005 Introduction to Chemical Engineering Thermodynamics, having been translated into four languages, had reached average yearly sales of 20,000 copies, with a total sales over all six editions exceeding a half-million, is “the best-selling textbook in the history of chemical engineering”. [4]

American physicist Herbert Callen's 1985 Thermodynamics: an Introduction to Thermostatistics is one of the most-cited books in the physics community (the 2006 edition being cited over 1220 times). The popularity of Callen's textbook, the second edition to his 1960 textbook Thermodynamics: an Introduction to the Physical Theories of Equilibrium Thermostatics and Irreversible Thermodynamics, is due in large part to the popularity of Callen’s 1951 paper “Irreversibility and Generalized Noise”, written with Ted A. Welton, a friend of Richard Feynman's at MIT, which by 1955 had become a “citation classic”, having been cited in over 370 publications. [2]
