They are, indisputably, excellent. They’re always good craft-centered pieces (which is no surprise given that the series is “The Art of Fiction,” “The Art of Poetry,” etc.), but I suspect that even if you never felt the urge to write anything yourself, if you were interested in that particular writer’s work you would get a lot out of each one.
No surprise, then, from reading this Lorin Stein guest post (at Ta-Nehisi Coates’ Atlantic blog) on the topic, that these interviews are the product of an involved and methodical process.
Here’s a link to the interview archives. Not many are available in full, but lots of the excerpts are meaty enough in and of themselves (and, you know, it’s fair enough that the Paris Review should want to sell issues, back or otherwise). This (excerpt from an) interview with James Ellroy is a beast, and prompted me to go to a bookstore and read the entire thing, which was equally beastly.
