Ask HN: Scanning a Closed Notebook/Book?

Hi. I was just looking at the post regarding the Vesuvius Challenge - scanning old scrolls for readable text.

I'm wondering if this is possible for notebooks. I often use pen and paper and fill small notebooks up quite quickly. I'd prefer not to scan/OCR every page individually.

Are there any methods that could potentially scan the notebook as a whole and parse the text inside? Maybe if using a special pen?

Any thoughts?
