So for the example that I believe Mr. Nordal gave about copying half of the book and giving it to the entire classroom, it seems to me that when I read the factors here, at least five of the six factors would come into play. Now, the character of the dealing talks about a single copy or multiple copies, so there's one. Both the amount of the dealing and the importance of the work allegedly infringed are to be considered, so the amount of the dealing would come into play there.
With regard to alternatives, is there a non-copyrighted equivalent of the work? Well, there is not, so that would come into play. On the nature of the work, if it has not been published it may be more fair. Well, it has been published, so that would come into play in the effect of the dealing on the work. We're talking about five of six factors coming into play.
It sounds as though Mr. Swail would want to wipe out four of the five and just have the one factor.
