Dear Colleagues,

We are in the presence of a functor F: A --> B which is
surjective on the objects of B, up to isomorphism. 
I suppose I could call such functors ``soouti'',
but I am hoping that someone will suggest a better name.

Somewhat related, I have not been able to discover the
definition of ``essential image'' in print,
and I would greatly appreciate a reference, preferably the first one.

Thank you very much in advance!

Cheers,
David
