Books:
Piano maintenance and tuning:
Pianos Inside and Out
by Mario Igrec. An outstanding reference on everything about pianos. Highly recommended.
Tuning methodology:
On Pitch: The Integration and Equation of Aural and Electronic Tuning Techniques
by Rick Baldassin (A small 112 page paperback with a lot of useful insights, but not worth ~$200 on Amazon)
The Craft of Piano Tuning
by Daniel Levitan (an excellent book that jumps straight into inharmonicity in chapter 2)
Different Strokes: Hammer Techniques for Piano Technicians
by Ken Burton. (a great compendium of hammer methods)
The Theory and Practice of Piano Tuning
by Brian Capelton.
Temperaments:
Tuning: Containing the Perfection of Eighteenth-Century Temperament, the Lost Art of Nineteenth-Century Temperament and the Science of Equal Temperament
by Owen H. Jorgensen (the ultimate source on historical temperaments)
Temperament: How Music Became a Battleground for the Great Minds of Western Civilization
by Stuart Isacoff (an excellent history of temperament, but lacking in a clear explanation of the math)
The Seventh Dragon: The Riddle of Equal Temperament
by Anita Sullivan
Mathematics of Sound:
Musimathics
by Gareth Loy (an excellent text, but amazingly there is nothing on stretch and inharmonicity)
Interesting papers in the professional literature:
