The first part of this list offers decent basic information (Negril 101: The Basics)...but the rest of the link/list is 10 years old and is quite outdated...just so someone doesn't go looking for some of the businesses listed in that link...'cause many are no longer there.
It was interesting seeing some of the old places and how things have changed, but agree... even some the "latest" maps aren't accurate! Things change so quickly!
