This classification scheme attempts to demonstrate a method of controlling and organizing an indexing language for the physical forms of non-book media. The classification is based on the technique of facet analysis. It comprises a classification of the concepts of the subject with an alphabetical listing of the verbal descriptions of the subject. The link between these is provided by a numerical notation that acts as a short code statement for these concepts and descriptions. The basic groups within this classification are as follows: Visual media, which is divided into moving media and still media. Within the still media is the special medium consisting of objects that deal with geography. These are followed by the non-visual media, which is divided into sound media and those media used by information machines, e.g., punch cards, magnetic tapes, etc. Finally, there are the programmed media, e.g., a scrambled book or computer programmed instruction. The classification excludes all microform concepts and most of the concepts dealing with technology of non-book media. (MF)
