It takes about 5-10 minutes for a typical paperback. A fat one might take 20 minutes tops. I am a fidgety person and cannot sit still, so I keep my hands busy and scan a book while I watch the news on TV. I use a stack slicer and a Fujitsu duplex scanner.

Is that legal in many jurisdictions? Format switching for music seems to go back and forth, I imagine this would be covered by the same rules.
