This is the 2002 edition. The current edition (2007) has significant changes (and yet already needs updating). Some might prefer the line drawings of the 2002 edition over the photographs in the 2007 edition.
Addendum: Here it is 2014 and we're still waiting for this to be updated. It really should be updated at least every 5 years, perhaps using the 5 year cycle of the American Heart Association guideline updates.
