I got a copy of the 30-year old book from EBay or Amazon for $20, chopped the spine off, and fed it through a scanner. Doing that to a century-old book feels wrong!
ScanTailor was tricky to start with; dunno if there's a manual. I remember belatedly realizing that there's automation at each step, that one can then quickly skim and manually adjust.
For collaborative editing, git via GitHub worked for us. Tracking who did what, and when, is easy. It allowed for sweeping edits covering multiple chapters. Building some porcelain on top of that, for less technical folks, could be good.
