ISBN for several books?

[Andrea]

I think that the ISBN listed for this edition (9788496208421) is also being used for all books in the series (is there such a thing as an series-ISBN?) because when searching on WorldCat (http://www.worldcat.org/search?q=9788...) the results show the first 4 books in the series...
In any case, it might cause some confusion.

It could be that these books were sold as one set with one ISBN, not as separate books. If that is the case, they should not be listed as separate books, but as the whole set.

OK, I've looked and found a couple of places where they mention that this is the ISBN for the "obra completa" (complete series), which should be confusing to add, as the series is not yet completely published and all that... I'm guessing that they aren't actually sold as a pack (haven't seen them in bookstores and also seeing that the ISBN has been in use before the latest book was published).

This particular edition is probably just mistakenly used as the ISBN for the Spanish edition of A Dance of Dragons (matches the rest of the details).
I'm guessing that these two should be merged then?

Hi! Can someone else comment on this?
I think that the two editions mentioned should probably be combined, but should we do something about the ISBN that stands for all 7 books? (like create a new edition for it?)
