The Buenos Aires International Book Fair (Spanish: Feria Internacional del Libro de Buenos Aires) is held every April in Buenos Aires, Argentina, and is one of the top five book expos in the world, oriented to the literary community as well as to the general public. Organization The expo is organized by the Fundación El Libro, a non-profit established by the Argentine Society of Writers (SADE). The fair is held each April month, lasting for nearly three weeks. There are stands distributed in eight halls, for both national and international publishing houses, countries, communities and Argentine provinces, and national and international institutions and organizations. Each annual fair has a specific motto. The fair, open to the public, is preceded by meetings and conferences of editors, publishers, translators, booksellers and other people from the publishing business. Other conferences are aimed to the educative fields and to librarians. History Although the fair was established in 1975, it was not the first book fair held in Buenos Aires. Earlier fairs were held at plazas, venues, or the Buenos Aires Cabildo. There was a great fair in 1930 at the Plaza de la República. Those fairs, however, were not held in regular periods. The SADE sought in 1971 a way to encourage the publishing business in Argentina, promoting more than 35 fairs in the 71-74 period. Those fairs, hosted as well at other cities of Argentina, were not limited to sell books, but included as well poetry, theatre, music or ballet performances. The SADE called most editorial houses of Argentina in 1974, and organized a new fair in closed quarters rather than in the street as it was done so far. Thus, the first fair of this type was held in March 1975 and was for years known as the "Buenos Aires International Expo, from the Author to the Reader". The first fair was held in the Centro de Exposiciones de la Ciudad de Buenos Aires, a utilitarian building in the Recoleta borough of 7,500 square meters, with 50 noteworthy authors, 116 stands from 7 foreign countries, and received 140,000 visitors. The fair has been hosted in recent years by the Argentine Rural Society in its Palermo borough expo grounds, of nearly 45,000 square meters. The number of stands has increased to 1,500 from 50 foreign countries, and the public is estimated to be nearly the 1,200,000 annual visitors. The 2011 fair was opened
