Determine subject, write its notation3.2 Done 3.2 goes on the spine of the book, it is the one descriptor assigned. The result is no different from the system where all the precombined descriptors are enumerated, but the display of the classification requires only 15 (grade levels) (subjects) = 115 lines One more example: Classification for shelving books or filing materials in a vertical file Facet A.
