The Dua Libro de l' Lingvo Internacia (Second Book of the International Language) was the second publication to describe the international language Esperanto (then called Lingvo Internacia, "international language"), and the first book ever to appear entirely in Esperanto. It was published in Esperanto in Warsaw in 1888 by Dr. L.L. Zamenhof, shortly after the publication of his Unua Libro.
