Fragrances of the World is considered to be the ultimate fragrance bible. As the world's most comprehensive customer selection guide, the annual Fragrances of the World listings provide a unique overview of international fragrance activity. The 2009, 25th Anniversary Edition, classifies over 6,500 fragrances and adds more than 800 new releases. It is the only guide to list niche fragrances as well as limited editions. The new edition is dedicated to Pierre Dinand, the father of modern perfume bottle design, with whom Michael shares a studio with in Paris. Since 1960, Pierre has created more than 700 perfume bottles. Some of his most famous creations, such as the bottles for Opium, Pleasures and Obsession, are featured in the book, illustrated by his drawings. Leading retailers such as Sephora and Nordstrom rely on this fragrance bible to help find the right fragrances for customers and suggest perfect alternatives when requested fragrances are not in stock. Bottom line: If you don't use Fragrances of the World you simply will not sell as many fragrances as you potentially could.
