Why? If you read an article that refers to other publications either in the body of the text or in footnotes you do not automatically get a copy of the publication to which reference is made. You should expect to pay for it. In your scenario if someone refers to a book, play, movie or game, then they have to buy you a copy or a ticket, or the original author should provide it gratis. You should be grateful that Beagle posted a link to where the information could be bought.
