In a -page book drawing of a graph , the vertices of are placed on a line and each edge is completely contained in one of fixed halfplanes whose boundary is . The line is called the spine and the halfplanes are called pages. The -page book crossing number of the graph is the minimum number of edge-crossings over all -page book drawings of . Book crossing numbers have been studied in relation to their applications in VLSI designs. In this talk, we present an overview and latest results on the -page book crossing number of the complete graph on vertices.
