Mathematical Olympiads 1997-1998: Problems and Solutions from around the World

This book is an absolute must have for those of us who love challenging mathematical problems. The book claims in its preface to be a continuation of Mathematical Contests 1997-1998: Olympiad Problems and Solutions from around the World, published by the American Mathematics Competitions. I made more than one attempt to find a copy of that book when preparing this review and was unsuccessful. (I have now been informed that the books from 1995-1996, 1996-1997, and 1997-1998 can be ordered from the American Mathematics Competitions web page.) We are fortunate that the Mathematical Association of America has decided to begin a new series of books, the MAA Problem Books Series, and has begun that series with this wonderful collection of problems from around the world.
