The 41st Buenos Aires International Book Fair takes place April 21 to May 11 at La Rural, fairgrounds in the Argentine capital.

Billed as “the most important annual literary event in the Spanish-speaking world” by the event’s organizer, Fundación El Libro, the Buenos Aires International Book Fair begins with special sessions open only to book professionals, from April 21 to 23.

These sessions offer “an outstanding training program, the best business opportunities and chances for networking,” Luciana Weiss, communications manager at Fundación El Libro, wrote in an email.

The fair opens to the public on the evening of April 23, and fair organizers are expecting 1.2 million visitors during the event, which will include more than 500 exhibitors and more than 4,000 publishing houses. The fair will also include, according to Fundación El Libro’s website, “a complete cultural program,” including readings and workshops.
