The Frankfurt Book Fair (German: Frankfurter Buchmesse, FBM) is the world's largest trade fair for books, based on the number of publishing companies represented. It is considered to be the most important book fair in the world for international deals and trading. The five-day annual event in mid-October is held at the Frankfurt Trade Fair grounds in Frankfurt am Main, Germany. The first three days are restricted exclusively to professional visitors; the general public attend the fair on the weekend. Several thousand exhibitors representing book publishing, multimedia and technology companies, as well as content providers from all over the world gather in order to negotiate international publishing rights and license fees. The fair is organised by Frankfurter Buchmesse GmbH, a subsidiary of the German Publishers and Booksellers Association. More than 7,300 exhibitors from over 100 countries and more than 286,000 visitors took part in the year 2017. History The Frankfurt Book Fair has a tradition spanning more than 500 years. Before the advent of printed books, the general trade fair in Frankfurt was the place for selling handwritten books, as early as the 12th century. A printers' and publishers' fair became established sometime in the decades after Johannes Gutenberg developed printing in movable letters in Mainz near Frankfurt; although no official founding date of the Frankfurt Book Fair is documented, it had definitely been established by 1462, the year that the printers Johann Fust and Peter Schöffer, who had taken over Gutenberg's printing operations after a legal dispute, moved their operations to Frankfurt. The fair became the primary point for book marketing, but also a hub for the diffusion of written texts. During the Reformation, the fair was attended by merchants testing the market for new books and by scholars looking for newly available scholarship. Until the end of the 17th century, the Frankfurt Book Fair was the most important book fair in Europe. It was eclipsed in 1632 by the Leipzig Book Fair during the Enlightenment as a consequence of political and cultural developments. After World War II, the first book fair was held again in 1949 at the St. Paul's Church. Since then, it has regained its preeminent position.
