<1991 revision> O88 PHENOMENA & ENTITIES * This class is for phenomena or entities treated from a multidisciplinary or non- disciplinary point of view. It is to be used only when emphasis on one discipline is lacking. The content of this class will be mainly materials and organisms * For human needs and activities from a multi- or non-disciplinary point of view, see 470 to 478 * For phenomena, materials and devices seen from both the pure and applied science points of view, see 610 to 890 * To specify a given material or organism from a multi- or non-disciplinary point of view, add after 088 the BSO number for the material or organism within the discipline which covers those properties which define the material or organism uniquely, e.g. 088,225,80 Liquids * In all their aspects * Liquids are uniquely defined by properties covered by the discipline of Physics, within which Physics of Liquids is coded 225,80 088,235,50,1-2,8 Water * In all its aspects * Water is uniquely defined by its formula representing properties belonging to the discipline of Chemistry, within which Chemistry of Water is coded 235,50,1-2,8 088,265 Air * In all its aspects * Air is uniquely defined as the material constituting the Earth's atmosphere and coded 265 088,275,40 Soil * In all its aspects * Soil is uniquely defined as a material forming part of the Earth's solid surface, an aspect covered by the discipline of Geology, within which Soil science is coded 275,40 100 KNOWLEDGE GENERALLY * Use only for the most general encyclopaedic interests 100,70 Dissemination & popularisation of knowledge 112 PHILOSOPHY * For religion and atheism, see 970 to 979 * For philosophy applied to particular fields of knowledge.
