I notice that nobody is getting up in arms about the Star Wars lines, or other popular works. I wonder why that is? They've been mentioned several times, even immediately after the chapter. As far as I'm aware, Alf has never attributed any of them; and yet, Lev Grossman's case is apparently the only one worth being upset over.
I also don't see what's so different about music or film; they're all intellectual property.
Actually, that would be the musical equivalent of taking an entire book, replacing the author's name with yours, and renaming it. The musical equivalent of what Alf did here would be no longer than a couple of measures.The musical equivalent would be recording someone's symphony with your own musicians, calling it a different name, and distributing it with you as the apparent author.
To the people saying that large numbers of years passed between other copiers of intellectual property: I didn't realize that the passage of time influenced how much of a work was taken from others. How long ago does someone have to have died for it to be okay to reference their work without attribution? Why is it that time passing makes it more okay?
And, perhaps most importantly, why is this important to anyone who hasn't bothered to read the work being discussed? Why is this issue so important when you have literally no stake in it?
