Discrete Approaches to Quantum Gravity
The construction of a consistent theory of quantum gravity is a problem in theoretical physics that has so far defied all attempts at resolution. Reviewed here are three major areas of research: gauge-theoretic approaches; quantum Regge calculus; and the method of dynamical triangulations.

How far are we from the quantum theory of gravity?
An assessment is offered of the progress that the major approaches to quantum gravity have made towards the goal of constructing a complete and satisfactory theory. The emphasis is on loop quantum gravity and string theory, although other approaches are discussed.
