In this paper we discuss about Near product cordial labeling graphs on Book graphs. If the labeling in the graph satisfies the condition of Near product cordial then it is called Near product cordial graphs. In this paper we have proved that the above mentioned graphs are Near product cordial graphs Except B+K1.It is not Near product cordial for both even and odd rectangular pages but for Triangular Book and Pentagonal Book it is not Near product cordial when t is odd.
