From Business Insider:
The first step to creating a quintessential Assouline library is, of course, getting in touch with the Assouline publishing house.
Founded in 1994 by Martine and Prosper Assouline, the publishing house is known for creating some of the most luxurious — and expensive — private libraries in the world, in addition to publishing some of the chicest coffee-table books.
Assouline’s books, which range from $75 to $1,000, are highly researched and honor various well-known people, places, and businesses. The most recent catalogue offers books on subjects including cigars, Rolex watches, feminism, and the Amalfi Coast. These books often take years to produce and sometimes come bound in silk cloth and velvet.
