Start typing.
With a digital camera and some setup, you could photograph the pages just as many photograph slides and photographs, but there's more than likely going to be a lot of page curve distortion on the edges, or you'll have to damage the book to get it flat enough that OCR might be able to work with it to get to text. If you've got a scanner you can go that route, but I'd be worried about damage trying to get it flat enough that it can convert into text again. Most scanners will just scan to PDF, but I hate PDF so forget I said that.
Out of curiosity, what book? I'm assuming that it's unavailable as an e-book because unless the book was very short, the time and effort involved would not be worth the cost, even at Canadian/Australian agency prices.
