The British Library has digitized one of Leonardo Da Vinci’s notebooks, and has put it online for the world to see.
The library has also digitized and posted the manuscript of Beowulf, the Harley Golden Gospels, the Silos Apocalypse, the Golf Book and the Petit Livre d’Amour.
You can find it all at The British Library’s Digitized Manuscripts page.
