It’s not new but it is certainly an interesting way to present digital versions of manuscripts and worth a look if you haven’t yet visited the site. The British Library offers “turnable” pages (somewhat like what you get with the Zinio reader) for historic manuscripts—requires Shockwave but it is slick. Fifteen great books are offered: Sketches by Leonardo, Mozart’s musical diary (shown above), the original Alice in Wonderland, and more. The magnifier is a really nice addition to the interface.
