After briefly discussing systematic ways of studying inhomogeneous cosmologies, we propose the technique of ''intrinsic symmetries,'' in which restrictions are placed on submanifolds of space--time. This leads to a broad classification of inhomogeneous cosmologies, and to an associated specialization diagram. By enforcing additional restrictions we obtain a further useful specialization.
