A large-scale literary fair that brings together publishers, authors, bookstores, and readers in a physical event. In Brazil, the most important biennials are the Bienal Internacional do Livro de São Paulo and the Bienal do Livro do Rio de Janeiro, which occur every two years and attract thousands of visitors. These events offer book launches, autograph sessions, lectures, debates, and cultural activities, serving as an important opportunity for networking among publishing professionals and for fostering connections between authors and readers.
