"This huge monograph surveys recent development in the rapidly growing area of discrete oscillation theory. It summarizes the results of almost three hundred research papers including background material, full proofs and hints with respect to the original literature. The easy level makes it suitable not only as a valuable resource for researchers, but also for undergraduate students. Personally I missed results on the connection between discrete oscillation theory and respectral theory. Nevertheless I find it a useful contribution to the literature in the field by four of the leading experts" --Book Review published in Monatshefte für Mathematik; Vol. 150, No.1/2007; by G.
