Imagine the following scenario: you are at a law library, searching for a German public law journal. You want to use it to marshal an effective argument about the German constitutional court. You start browsing bookshelves. After some minutes, a thought occurs to you that that this library is not located in Germany, but in Rome or Amsterdam. The journal you are looking for is, of course, published in German. Is it available at all? From the corner of your eye, you see German legal journals popping up. All is good.
