Here it is: The Physical Principles of the Quantum Theory by Werner Heisenberg, published in 1930 by the University of Chicago, 186 pp (but the format is 5 3/8 x 8 inches). Translated into english by Carl Eckart and Frank Hoyt of the UC Dept. of Physics. Original cost: $1.25. It's the paper-bound "Student's edition"-- the hardbound ed is mentioned on the inside front cover as costing $2.50. I paid 50 cents for it. Isn't that amazing?

Actually, this is a monograph Heisenberg developed from a series of lectures he gave on quantum physics at UC in the late 1920's. It has a chapter on his uncertainty principle.
