Does anyone know where I can order portuguese translations of Bradbury's works?
This would be a big help.
Thanks.

I suggest going to the Advanced Book Exchange website at http://www.abebooks.com.

Do a search by typing in Ray Bradbury's name as the author, and with Portugal entered as the country code so that your search will be confined to Portugese bookstores. I think you may come up with a handful of Ray's books in Portugese (since I personally am unable to translate the language used to describe the list of books that appears after such a search, I can't be sure that the books are in Portugese). You can order the books right from the ABE site.
