The world’s largest annual trade show for the book publishing industry, held annually for five days in Frankfurt, Germany, attracts exhibitors from about 110 countries and is attended by more than 250,000 people. Trade fairs have been a tradition in Frankfurt for at least 800 years, and book fairs were held in the 16th century, when the city had become the center of German publishing. The book fair had been chiefly an event for German publishers before 1939, but it grew in a few years to be the world’s preeminent book fair. In its present form, the fair is officially dated to 1949. Discuss
