On my last visit to London (on business; good thing financially speaking), I visited the British Library for the first time. The Sir John Ritblat Gallery is a permanent free display of ancient books, including early literature and holy books; maps, the Magna Carta, writings of Shakespeare and an array of literary giants, an impressive Beatles display and much more.
It’s a must see exhibit, but you can experience the Diamond Sutra, the oldest printed ‘book’ (printed in China in the year 868), online, courtesy of the British Library’s outstanding Turning the Pages site. In fact, the actual Diamond Sutra is so fragile it is not on display; library visitors instead view it and other pieces using a large touch screen very similar to Turning the Pages.
You can scroll through the Diamond Sutra (literally; it is a scroll and not a “book”) with a text or audio narration about one of the most important sacred works of the Buddhist faith.
