Book fair — facts & figures
The Frankfurt Book Fair, the largest, oldest and most important book fair in the world, brings (29) an estimated 80,000 executives from the international book and media industry, (30) nearly 10,000 journalists from about 70 countries report (31) the event.
To begin (32) , the Frankfurt Book Fair was primarily an order fair (33) booksellers from Germany but, as its international importance grew, the (34) of rights and licenses became its central activity. (35) three-quarters of the publishing world's rights and licenses (36) now transacted through the Frankfurt Book Fair.
The Frankfurt Book Fair has responded to the development of the electronic media by, in 1993, setting (37) a separate exhibition area at the fair. (38) two years, the number of exhibitors Offering electronic publishing products increased eight-fold, (39) that now the Frankfurt Book Fair is the most important event in the medium of electronic publishing (40) well as books.
