I would imagine that if one attaches an ISBN to a document then that 
document must be considered TOTALLY FROZEN, so otherwise the ISBN would 
not be a useful unique identification. I would certainly feel upset if I 
told my students what book to buy and went to the trouble of telling them 
what ISBN to check for and found that what they bought differed in even 
the most minor way (eg pagination) from the version I based any of my 
course handouts on. So I think you will all need to decide just how 
stable the book wants to be how soon... oe whether people will want to 
keep adding in updates and improvements...
