In The Oxford Handbook of United Nations Peacekeeping Operations, editors Joachim A. Koops, Norrie MacQueen, Thierry Tardy and Paul D. Williams offer a major reference work that provides factual details and evaluations of each UN peacekeeping operation deployed up to 2013. Comprised of seventy-two chapters and over nine hundred pages in length, this is an invaluable study for scholars interested in the history and outcomes of peacekeeping, writes Gary Wilson
