"This volume provides a wealth of information to satisfy the most specialized of collectors but is easily used by beginner collectors as well. Since it is published only every three years or so, it is easily affordable by libraries and would make a valuable addition to library shelves as well as to the collections of individual stamp enthusiasts. With its sound foundations, superb scholarship and high standard of production, I have no hesitation in recommending this title." - Aileen Wortley, Manitoba Library Association
