Heritage • There are two types of ‘width of knowledge.’ One is knowing as much as possible of what is going on now. The other is knowing how we got to where we are – what is the heritage of ideas and practice on which we may draw. • Vickery, B. C. (2004). A long search for information (Occasional Papers, No. 213). Graduate School of Library and Information Science, University of Illinois at Urbana Champaign. Footer
Three groups: • Library Research Circle (India) 1951 • Classification Research Group (UK) 1952 • Classification Research Study Group (North America) 1959 • As far as general libraries are concerned, classificatory research in the USA has taken a less spectacular form (than in Great Britain). • Yet it is interesting to note that a [USA] Classification Research Group was set up … in 1959; possibly there will be a slow recognition of the value and techniques of facet and phase analysis.” • Sayers, W.C.B. (1967). A manual of classification for librarians. 4th ed. London: Deutsch. p. 375.

“Low-hanging fruit”? • Hearst (2008) • “facets refer to categories used to characterize information items in a collection.” • Reamy (2009) • “facets are often derived by analysis of the text of an item using entity extraction techniques or from pre-existing fields in the database such as author, descriptor, language, and format. This approach permits existing web-pages, product descriptions or articles to have this extra metadata extracted and presented as a navigation facet” Footer
Strengths of facet analysis • Theory drawn from practice • Foregrounding • domain interests • information seeking strategies • tasks • domain vocabulary Footer

Facet analytical approach: Footer • Proper and rigorous practice of facet analysis by observing the rules of logical division. (Broughton, 2001, p. 67; Mills, 2004, p. 268). • one characteristic of division is applied at a time [conceptual analysis] • division steps should be logical and proximate • division should be exhaustive (Mills, 2004, pp. 551).
Planes of work • Idea: The work of FA takes place in the Idea plane, where an entity is analyzed into component parts • Verbal: FA continues here as further sorting and transformation of the selected categories/facets or terms occur. • Notational: work of FC -- translating selected terms into notation.
Facet Analysis (FA)Faceted classification (FC) FA - (analytical technique) • Listing of characteristics of the entities in a universe (exhaustive, mutually exclusive) FC - (synthetic structure) • Division of entities in a universe (by one characteristic at a time) FC – (structure of synthesis) • Synthesis – combine relevant facets: • Schedule of terms for description • Assignment of notation
Background FA/FC • Universal Decimal Classification • Otlet, La Fontaine -Documentalists • 1904-1907 – scheme published • Bliss Bibiliographic Classification • Henry Evelyn Bliss • 1908 (practice) 1923-1933 (theory) • Colon Classification • S.
