%0 Journal Article %T The Thermodynamics of Black Holes %A Wald Robert M. %J Living Reviews in Relativity %D 2001 %I Max-Planck Institute for Gravitational Physics %X We review the present status of black hole thermodynamics. Our review includes discussion of classical black hole thermodynamics, Hawking radiation from black holes, the generalized second law, and the issue of entropy bounds. A brief survey also is given of approaches to the calculation of black hole entropy. We conclude with a discussion of some unresolved open issues. %K Quantum General Relativity %U http://www.livingreviews.org/lrr-2001-6
