on september 10th rio celebrates 'press day' in honor of johann gutenberg, the inventor of the printing press, and hosts the rio de janeiro's international biennial of books, the bienal do livro.

Johannes Gutenberg, a brilliant 14th century German, is credited with the breakthrough technology used to print books in series with movable type.

up until then, books were reproduced by hand-writing each individual copy, until Gutenberg's printing machine inaugurated the technology with the creation of the Gutenberg Bibles - pressed on fine paper and velum and hand-painted, these bibles were the first major book printed in the west with this modern technology.

the bienal do livro is one of the largest literary events in brazil - a large gathering offering readers the opportunity to get closer to their favorite authors, and discover many others.
