The site as an AI agent gets it, beside the site as a person sees it. What it can read, what it has to cut away, and what it never sees.

Now, his letters have been collected and published, illuminating as never before the intimate side of a private genius. Hunter Davies, author of the only authorised biography of The Beatles, has tracked down almost three hundred of Lennon’s letters and postcards – to relations, friends, fans, strangers, lovers and even to the laundry. Some of the letters are tender, informative, funny, angry and abusive, and some are simply heart-breaking – from his earliest surviving thank-you note, written when he was ten, to his last scribbled autograph given on 8 December 1980, the day he was shot, aged forty.
