Graph labeling is one of the fascinating areas of graph theory with wide ranging applications. Graph labelings were first introduced in the 1960s where the vertices and edges are assigned real values or subsets of a set subject to certain conditions. Motivated by the notion of magic squares in number theory, magic labelings were introduced in graph labeling. The concept of H-magic coverings and H-magic labeling emerged in 2005. H-magic labeling is the generalization of magic valuation defined by A. Rosa. In this book a variety of graph families that admit H-supermagic labelings are studied. Some H-supermagic graphs are constructed from well known graphs. This book throws some light on the H-supermagic strength of some graphs also.
