When attempts to find information fail, patrons
may choose to approach the reference desk.  If
they do, the librarian becomes the human
interface or mediator between the library and the
users’ need.
l The critically important moment when users approach
and engage the librarian can be the point at which the
complexities of the library are gently explained, fears
are calmed, and information becomes accessible.
l If help is withheld, given grudgingly, hurriedly, or in a
condensing manner, the encounter becomes the point
at which the library appears even more inaccessible.
Users can be left feeling confused, frustrated, and
sometimes personally defeated or humiliated.
