Review:  Let G and L denote two graphs. By \chis(G < L) we mean the minimum number of colors required to color the vertices of G so that any subgraph of G isomorphic to L has all of its vertices assigned different colors. Given integers n and e,

\chis(n,e,L) = maxG in G{\chis(G,L)}

where G is the class of all graphs on n vertices with e edges. Thus, \chis(n,e,L) is an ``extremal anti- Ramsey number''. This paper is devoted to the study of these numbers. It contains some specific values, some bounds and some asymptotic results. It closes with a discussion of several interesting open questions.
