Summary

This volume contains the proceedings of the 12th triannual International Conference on General Relativity and Gravitation, the premier conference for presentation and discussion of new ideas in relativity and cosmology. The volume contains invited talks in addition to short reports on the parallel workshops that took place at the meeting. It is essential reading for all research workers in relativity, cosmology and astrophysics.
