The Dorotheum is based in Vienna, Austria, but its sales go far beyond that nation's borders. It is Europe's leading German-speaking auction house. The firm traces its roots back over three centuries to its founding in 1707. It now has over 700 employees, including 200 abroad, and operates around 600 auctions per year, with annual sales well over €100 million.

Among the many items featured in their auctions are art, antiques and collectibles, furniture, and jewelry. Naturally, many books and related works on paper are also found in the many auctions run by this large firm.
