Q: Do you mean my link, to the libretto? It works fine for me, and takes me directly to the page in the book that contains the lyrics I copied. No, I don't think you have to join anything, but it might depend on what country you're in. Google attempts to make these texts available only in those countries where it determines the works are no longer under copyright, although I think they don't always do this correctly. We have found instances where certain books are viewable by users in the USA but not in the UK.
