“…This technique has been a favorite for organizing structures via functional segments or defined substructures. 10,23 The central part of the figure illustrates the linear notation in which the complete structure is coded by ciphers; for retrieval, cipher symbols are selected and matched. Particularly where the file includes numerous compounds with closely related structures, ciphers are used as a convenient method of organization both for identification and for collecting compounds with specific features.…”

To chemists, graphic structures are descriptions of reality which not only identify chemical compounds but also convey relationships concerning functions, reactivity, and properties. Chemical formulas and structures also are essential methods of entry through which information is located or correlated in the body of chemical knowledge, but practical methods have not been available for indexing structures, in contrast to indexing representations of them which are further abstractions of chemical reality. Furthermore, bulky structures cannot be printed conveniently with conventional linear type and they have no inherent equivalent for speech. Therefore, chemists and documentalists have devised a variety of descriptive codes or representations to record and communicate chemical structures and the compounds they portray. These methods include nomenclature, structure hierarchy, fragmentation, cipher notation, and topological coding.
