I’m not sure if these are only available in the UK, but at SimplyMoleskine.com, they’re offering Volant notebooks in two new colors, and Volant Address Books:

New in February 2009: Volant Address Books in 3 sizes and 4 colours.
The new Volant Address Books have ruled pages with laminated alphabetical tabs, created to be light and handy. Available in extra small, pocket and large sizes.

[UPDATED: I just saw an announcement about these new products for the US on Moleskine.com]
