There ought to be sufficient space on a standard CD to have all the editions of the “Book of the Scott” included. Or such editions as fortune allow to be gathered for scanning. That is unless you figure on capturing the fibrous nature of the paper it is printed on! Really though at 0.5Mb per page (and you can probably do much better and still have good images), you can store 1400 pages on a disk. If you were scanning something that was predominantly photos, you might want to allow 1-2Mb per page. And I mean good photos, don’t waste that much file space on scanning half-tone images and line art, it is overkill.
But stop talking about that “Book of the Scott”, I want to hear more about “Made to the Limit Gage”!
