Stellar Classification is an important activity for astronomers, since it provides “systems” for comparison with new types of stars. A good classification scheme can be used cannily to segregate “peculiar” objects and to gain insight into the processes which generate “normal” objects. Eventually, when there are enough objects in a given “peculiar” class, the definition of “normal” can be extended to include them. Through the process of classification, prototypes can be isolated for detailed study, providing a short-cut to the lengthy process of studying all stars in detail. Thus, classification of stars and maintenance of the reference frames are important on-going processes in astronomy.
