  Recent results on solutions of the Einstein equations with matter are
surveyed and a number of open questions are stated. The first group of results
presented concern asymptotically flat spacetimes, both stationary and
dynamical. Then there is a discussion of solutions of the equations describing
matter in special relativity and Newtonian gravitational theory and their
relevance for general relativity. Next spatially compact solutions of the
Einstein-matter equations are presented. Finally some remarks are made on the
methods which have been used, and could be used in the future, to study
solutions of the Einstein equations with matter.
