"[I]n our opinion the amounts proposed by the Consortium, being 1 to 2 pages of a work, are reasonable approximations in establishing non-substantiality. However, since 1 to 2 pages of a short work can amount to a great portion of that work, we further limit this approximation by requiring that the copying of 1 to 2 pages not constitute more than 2.5 per cent of the entire work" (emphasis added) (par. 204).
