Design Observer - Michael Bierut's Notebooks

'25 Years, 85 Notebooks' is the simple title of Michael Bierut's post on Design Observer. Bierut gives readers a peek into his amazing collection of notebooks and talks about their significance in his life and work. A must-read for any notebook aficionado.
I nearly forgot to mention... I discovered the notebooks via Merlin Mann's excellent blog, 43 Folders. Merlin Mann has been writing on productivity for quite some time, and recently has moved his focus away from 'quantity' productvity and time management towards quality and priority: doing what matters, and doing it well.
