I like this idea . I too have acumulated 100s of DVDs , Cds and books . With my DVDs , I have to say that it would be a case of lending them out .. I have many DVDs from here in Spain that I know I couldnīt access in the UK . My DVDs are important to me . And I would probably have to say the same for my books and CDs .
I would be happy to lend my "collection" out but I guess I would need to reference them first . But this is a fledgling idea and I think it could work out well for those living in or around Madrid .
