The review covers the classification of porous materials, and the properties expected from the solid and the adsorbate within the pores. Rather than dealing, in what would inevitably be a seed-catalogue manner, with different solids, an attempt has been made to give a thorough introduction to the subject as a whole. The reader can then follow up particular avenues appropriate to his needs. Examples of porous carbons are used to illustrate the kinds of phenomena expected more generally with vapours adsorbed by porous solids. Capillary phenomena become evident when the adsorbate within the pores is liquid-like, and curvatures of fluid/fluid interfaces are important, e.g. with adsorption in macropores or the displacement of one liquid by another. Structural damage which can arise from vapour adsorption, or from phase changes of capillary fluids (e.g. frost damage to building materials) is surveyed. The literature cited covers main publications, or those providing a useful insight (with their own lists of references), especially from the past 30 years, but the subject is old, and some references cover the 19th Century. Flow of liquids is largely omitted except for general introductory references.
