Under Health/Mental Health is a Self-Help guide on the Open Dirctory Project (DMOZ).

Dr. Clay tucker-Ladd is a clinical psychologist. Here is his notion of "self-help:" I consider self-help to be intentional coping. It is handling your own troublesome situations by exercising deliberate conscious control to improve the outcome of the situation. It is recognizing your own personal weaknesses and working to overcome those faults and improve yourself. It sometimes involves changing others or the environment to improve your own circumstances or feelings, but self-help primarily focuses on changing your own behavior, feelings, skills, cognition (thoughts), or unconscious processes. Self-help is the conscious reasoning part of your "self" changing other aspects of your internal self, your actions, and your situation. It is self-improvement by yourself.
