~ Moleskine Architectural book series

I think a design journal is an essential part of the designers life (and inspired this blog), for me the inspirations & references that inform the design process are essential & cannot wholly be replaced by the electronic version.  
Moleskin have published a series of design journals called Inspiration & process in Architecture. It features architects Zaha Hadid, Giancarlo De Carlo, Bolles+Wilson and Alberto Kalach including  drawings, sketches, scribbles, watercolors and personal notes from each designer. A great idea for any archiphile!
It follows the series dedicated to the design world which includes The Hand of the Architect (2009), The Hand of the Designer (2010) and The Hand of the Graphic Designer (2011).
