askSam Systems, is a company that designs and publishes text database and web publishing tools. They have just made a database of Leonardo DaVinci's notebooks freely available on the web. It is comprised of over 1500 pages filled with his ideas, thoughts and tips. Entries are strictly text - no drawings or sketches. It is a searchable database which adds to it's value. It is not a particularly attractive product in my opinion, but could be very useful for those interested in DaVinci.
