A-cordial labeling was introduced by Mark Hovey. He introduced A -cordial labeling for an abelian group as a simultaneous generalization of cordial and harmonious labeling. If A = V4, it is known as V4 -cordial labeling. Let V4 be the Klein-four group. In this chapter we prove some ladder and book related graphs which admit V4 -cordial labeling. We prove that Book Graph B(5, n), Mobius Ladder Mn Open Ladder O(Ln) and Mongolian Tent MT(2, n) are V4 -cordial graphs.
