 The Osmothèque is the world's largest scent archive, storing over 3,000 perfumes from the past and present, all preserved at a constant temperature under argon gas.Perfumes accepted into the collection are either those reconstituted using archived formulae by the Osmothèque's internal perfumers (known as osmocurators) or those supplied by external perfume houses.As a legal deposit archive, the Osmothèque receives a supply of all new perfumes produced in France and much of the world, in addition to those obtained through its program for content acquisitions.
