Wow, this was a find: it bills itself as "The DNA of Literature," which may sound meaningless, but the content of it is not. So what is it?
"It" is a collection of 300+ Writers-at-Work interviews, originally appearing in The Paris Review and subsequently collected in the series of books bearing the title Writers At Work. I still recall how excited I was, as a teenager in the Seventies, discovering the interviews in those books: actual writers, talking about how they worked their craft...ah, it was exciting. All of the 1950s interviews are online now, and free, and their plan is to have everything online by June 2005. Go take a look. (Hat tip to Butterflies and Wheels)
