Book in original Polish

[BentFranklin]

For a Polish friend here in the US I want to buy Polish-language versions of several of Lem's books.

1.  Where is a good online seller?  Preferably a US company, for import reasons, but not necessarily.

2.  Where can I see a list of English titles with their Polish names side by side?  I want to buy the right ones!

Thanks!

This isn't Stanislaw Lem, this is Stanislaw ULAM! How could you do this to other Robots, Oh King Krool!
