Podsumowanie	Faceted classification design is the constructive engineering of a complete analytico-synthetic scheme for a subject field, turning the conceptual technique of facet analysis into a working classification with facets, ordered arrays, a citation order, and notation. The methodology was codified by Brian Vickery for the British Classification Research Group in his 1960 guide to constructing special schemes, building on S. R. Ranganathan's theory of analytico-synthetic classification. Where facet analysis decomposes subjects into fundamental dimensions, faceted classification design assembles those dimensions into a usable, hospitable, and notation-bearing system, and then tests it against real documents. The result is a scheme that classifies compound subjects by synthesis, grows gracefully as a field expands, and underpins both shelf classification and modern faceted navigation.	Facet analysis is the analytico-synthetic technique, pioneered by S. R. Ranganathan and systematized for special schemes by Brian Vickery, for decomposing a subject into its fundamental conceptual components. Instead of trying to enumerate every compound topic in advance, the analyst breaks a subject down into elementary concepts (isolates), sorts those isolates into a small number of fundamental categories — in Ranganathan's canonical scheme Personality, Matter, Energy, Space, and Time (PMEST) — and arranges each resulting facet as an ordered array. A defined citation order then prescribes how facets recombine, so any compound subject can be synthesized from its parts. Facet analysis is the conceptual engine beneath faceted classification, thesaurus structure, and much modern metadata, taxonomy, and interface design.
