The volume 42 is devoted to Covered Solid Surfaces and, in particular, Subvolume A to Adsorbed Layers on Surfaces. It is as such a collection of data obtained for adsorbates on well-defined crystalline surfaces. 'Well-defined' means surfaces of known crystallographic structure and chemical composition. The present subvolume III/42A4 deals with: Adsorption of C, N and O on metal surfaces; CO and N2 adsorption on metal surfaces; H2O and OH on semiconductors; Cyclic hydrocarbons; Polyatomic chain-like hydrocarbons on metals and semiconductors; Adsorbate induced surface core level shifts.
