The Frankfurt Book Fair is the world's largest trade fair for books, based on the number of publishing companies represented. 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.

A trade show, also known as trade fair, trade exhibition, or trade exposition, is an exhibition organized so that companies in a specific industry can showcase and demonstrate their latest products and services, meet with industry partners and customers, study activities of rivals, and examine recent market trends and opportunities.
