The British Library has digitised and made available online two of Leonardo da Vincis' notebooks - called the Codex Leicester and the Codex Arundel.

The notebooks are made available online via the British Library's application 'Turning the Pages', which allows you to move and turn the pages as well as zoom in and rotate them.

Turning the Pages is an example of the kinds of projects being enabled and online content being made available through advanced research and education networks.

It is one of a number of projects that form part of the British Library's strategy to build a digital research environment; to digitise resources, collections and other valuable content and making them accessible and available online. This strategy is enhanced by JANET, the UK's advanced research and education network (see http://www.ukerna.ac.uk/). The broad take-up of JANET in the UK (18 million end users) means the Library is able to reach an audience of unprecedented size.

Both notebooks are freely available at the British Library website for the next five months .
