I tripped over an amazing archive of Paris Review writer interviews. They've been publishing these timeless gems for years, and they have some/most/all posted online, available as downloadable PDFs. Well worth checking out.
Can you guess which author said this: "During signing sessions my queue is always full of, you know, wild-eyed sleazebags and people who stare at me very intensely, as if I have some particular message for them.”
Which author dropped this nugget: "On the dangers of writing too much: 'By the eighteenth book, one has a sense of having bricked oneself into a niche, a roosting place for other people's pigeons. I wouldn't recommend it.'"
Okay, one more: “Another thing I need to do, when I'm near the end of the book, is sleep in the same room with it. . . . Somehow the book doesn't leave you when you're asleep right next to it.”
