Actually, Ed, this would not only make for a good blog post (please, so 
it doesn't get lost in email space), but I would love to see a 
discussion of what kind of revision control would work:

1) for libraries (git is gawdawful nerdy)
2) for linked data

p.s. the Ramsay book is now showing on Open Library, and the subtitle is 
correct... perhaps because the record is from the LC MARC service :-)
