BritishLibraryToday’s Follow Friday is about the new mobile phone app from the British Library called Treasures.

Over 100 rare items from the holdings of the British Library are available in high-definition images, including the original version of Alice’s Adventures in Wonderland, the world’s oldest bible, priceless hand-painted medieval books, Nelson’s battle plan for Trafalgar, sketches by Leonardo, a 1664 plan of New York, “The Tyger” in William Blake’s hand, and many others.

The app is arranged in seven browsing categories: Science, History, Music, Literature, Faith and Religions, Maps and Views, Illuminated Manuscripts. There’s something in each of those categories to delight any genealogist.

Treasures is available as an introductory price of UK £1.19 (US $1.99) for iPhone and Android smartphones, and UK £2.39 (US $3.99) for iPad until 24 Jan 2011.
