Luckily in our library system near San Francisco we have 12 copies and 12 on the waiting list. So no perishing from old age while waiting for a copy here.
I read the book, and it's a good one. There are also some articles and videos available on the Internet from Seymour Hersh's book tour that add to what's in the book. He thinks, for example, that Donald Trump may be an underrated president.
Sadly, it seems like there are no journalists like Seymour Hersh writing today. At least I can't think of any. He's become living history.
