The general problems of three-dimensional quantum gravity are recapitulated here, with emphasis on the mathematical problems of defining the measure of the path integral over all three-dimensional metrics. This work should be viewed as an extension of a preceding one on the four-dimensional case, 12 where some general ideas were also discussed in detail. We finally put forward some suggestions on the lines where one could expect further progress in the field.
