Review:  [For the entire collection see Zbl 638.00009.]
Let G be a graph of positive size q, and let n be that positive integer for which \binom{n+1}{2} \leq q < \binom{n+2}{2}. Then G is said to have an ascending subgraph decomposition if G can be decomposed into n subgraphs G1,G2,...,Gn without isolated vertices such that Gi is isomorphic to a proper subgraph of Gi+1 for 1 \leq i \leq n-1. Several classes of graphs possessing an ascending subgraph decomposition are described.
