The Institute published the "Normes ortogràfiques" in 1913, the "Diccionari ortogràfic" in 1917, and its official "Gramàtica catalana" in 1918. That same year, Fabra also edited the textbook "Curs mitjà de gramàtica catalana," published by l'Associació Protectora de l'Ensenyança Catalana. His "Converses filològiques," first published in the newspaper "La Publicitat," were later collected as "Popular Barcino." Probably his most famous work was the "Diccionari General de la Llengua Catalana" (1932), the first edition of which later became the Institute's official dictionary.
