Surfaces and interfaces are important for both science and technology. Stimulated and challenged by sophisticated experimental techniques applied to their study on well prepared and characterized materials, theory - especially local density electronic structure theory - has responded in what may be called a dramatic fashion. This paper describes some aspects of the present state of self-consistent all-electron local density theory for treating surfaces, interfaces and overlayers. Following a review of the methodology, results of detailed calculations on representative specific systems are presented which illustrate the important role of charge transfer; the understanding acquired from these studies will be described and discussed.
