The fashion designer Yves Saint Laurent once declared of his partner Pierre Bergé: “The world will talk about a Goût Bergé, just as it speaks of a Goût Noailles.”

As the $484 million auction of the couple’s art collection at Christie’s in 2009 can attest to, this “Bergé taste” is the epitome of a keen eye, and a penchant for objects with great history and pedigree. Over the next two years, more examples of Bergé’s fine collectibles are scheduled to go under the hammer in Paris, this time at Sotheby’s — in the form of 1,600 precious books, manuscripts and musical scores from his personal library that date from the 15th to the 20th century.
