Linked Notation

We thus follow Metcalfe, who had distinguished between ‘specification’ (basically, types of a thing), which should be handled by the creation of a hierarchy of subject headings, and ‘qualification’ (everything else: process, aspect form), which should be addressed through linked notation (Foskett The Subject Approach to Information. 5th edition. London: Library Association Publishing,1996,127).

UDC uses linked notation extensively, and is often criticized for unwieldy notation. Much of the problem stems from very long notation for simple subjects (because UDC builds upon DDC7). UDC may also sometimes put more detail in the call number than is required (Foskett 1996, The Subject Approach to Information. 5th edition. London: Library Association Publishing, 186)
