A copy of Shakespeare's First Folio, the original collected works of the playwright published in 1623, has turned up in the library of Scotland's Mount Stuart House on the Isle of Brute, and authenticated by a professor at Oxford University. That brings the total number of known surviving First Folios up to 234. They usually sell for £3 million or more at auction. Unrelated, but also interestingly, Mount Stuart claims to be the first home in the world to have a heated indoor swimming pool. It sounds like a truly great place.
