It depends. If you have a pure data-type, variables (fields) are 
ok.
But in an object (class) normally I'd rather nobody messes with 
the internal stuff. Its just too likely to botch things up. So, 
yes, in a library I prefer getters (setters not so much for the 
same reason).
But setters are still better than variables, as they don't allow 
to take the address of the field controlled by them.

Of course nothing can stop you from shooting yourself in the foot 
if you really try - but it should not be the first and easiest 
thing to do.
