Songbook dilemma

[Moz]

I have a dilemma. I have the Fleetwood Mac Deluxe Anthology with sheet music for the first three albums. I really want to scan everything and put it on The Ledge, but I'd have to take the book apart in order to do that, because it won't fit in my scanner or a photocopier because the edges get cut off.

It's falling apart anyway - the spine is ripped about 1/3 of the way down and some sheets are loose. Since it's already kind of gnarly, should I (carefully!) disassemble the book and scan the pages? Or should I just leave it as is? I don't know how easy these are to come by, and if I did take all the pages out, I'd want to buy a new one for sentimental purposes. What would you do?
