I'm a Chilean journalist and I wrote a book (in Spanish) about Dragon Ball in my country: "¡Vamos a buscar! El camino de Gokú en Chile" (Let's go searching! Goku's path in Chile). This investigation is about how Dragon Ball arrived to Chile and it's development trough the years: press, media, fandom, local music, social events and much more. It's a very, very local work and maybe only Chileans has interest on it, but... who knows. There is a huge Latin American community out there.

Best regards from Chile.
