My article Unocal at 20: Director Primacy in Corporate Takeovers, 31 Delaware Journal of Corporate Law 769 (2006), was reprinted in its entirety in I Law and Economics of Mergers and Acquisitions 449 (Steven M. Davidoff & Claire A. Hill eds. Edward Elgar Publishing 2013), along with many other fine (albeit lesser) articles. Granted, it's a bit pricey, but consider the priceless prose that would be at your disposal!
