Check out this Yale University Press published book, The Anthology of Rap. I just bought a copy myself for an awesome project.

I picked up this book at the NYPL Live event when I was fortunate enough to see Def Jam present this book. I even had it autographed... Woot! Woot! If you like Beastie Boys and Public Enemy, read this book. Check out some of the cover albums and screenshots of videos:
