Rare Books online at the British Library

The original Alice in Wonderland (with the hand-drawn pencil illustrations!) has just been put online by the British Library. The scans are displayed using Flash, so that the reader can "turn the pages" as they go.

There are also beautiful examples of Arabic and Jewish Calligraphy, as well as one of Leonardo DaVinci's notebooks.
