General Relativity and Gravitation. Vol.1-2 by A. Held (ed.)
These volumes offer a number of articles dealing with quantization and general relativity. Within this field there are several approaches. The oldest of these uses the canonical approach to relativity, a topic to which a large portion of Volume 1 is devoted. In addition to the article on quantization, other problems that are discussed using this formalism are the Cauchy problem, the positive mass conjecture, and the Hamiltonian structure of space-time. The necessary background is covered in an extensive review article.
Volume 1 also contains several articles expounding the gauge theory and the supergravity outlook. The more exotic approach through the use of twistors is described in Volume 2.
