What's the legality of this? That's a PDF of a recent, in-print book, on the site of someone who is not one of the authors but who is one of the interviewed mathematicians, and there do not appear to be any links on the site leading to this file or any mention of it.
My guess is that this is a courtesy copy of the ebook given to the site owner because he was interviewed in the book, and he probably did not intend for this link to be circulated.
BTW, this is one of a series of books of interviews with mathematicians by the same interviewers/editors. They are all very interesting.
