The Contest Problem Book IX is the ninth book of problems and solutions from the American Mathematics Competitions AMC 12 contests. It chronicles 325 problems from the 13 AMC 12 contests given in the years 2001 through 2007. The authors were the joint directors of this and the AMC 10 competitions during that period, and are also joint authors of a book that includes the AMC 10 exams from the years 2000 through 2007.
