This issue is several orders of magnitudes worse with ebooks.

The technical ability to reissue a book after correcting typo or other 
minor error in response to feedback means that the same work by the same 
author and publisher can have multiple editions per day during the 
release period. This is effectively a rainbow of shades between 
'uncorrected proof' and 'final edition'. I'm not aware of any 
bibliographic approach that currently deals with it effectively.

Publishing systems typically identify versions using a cryptographic 
hash function.
