With so much ink already spilled over Dylan … why this collection now? The answer lies in the first essay, by David Yaffe of Syracuse University. “If you’re reading this for Rock & Roll 101, take notes but do not plagiarize,” he writes. “Leave that to Dylan (but more on that later).” It’s built for college classrooms, a primer for people who were born into a world that didn’t need to invent Bob Dylan because he was already there.
