As aventuras de Pi - duplicate?

[Tatjana]

Heya,
I'm a new Librarian, so I apologize if this is in the wrong place and tell me what an more appropriate topic might be! :)
I believe this:
http://www.goodreads.com/book/show/17...
is a duplicate of this:
http://www.goodreads.com/book/show/17...

There may be another edition of this particular translation (I believe there are 2 translations), but this one has "Yan Martel" (sic) as the author and no further details beyond "Portuguese" as language. It actually seems to be a specifically Brazilian Portuguese; but, again, language is a caveat.

Someone with better Portugues do Brasil skills might correct this with more confidence. :)

Cheers and Best,
Tatjana

Combined authors and books. Looking into ISBN

Edit: Can't find any other edition except from the ones that already have ISBN, but I Don't speck the language so don't count on my opinion.
