Summary	Literary warrant analysis is the method of justifying the classes and terms of a knowledge-organization system by reference to the actual content of a domain's published literature, rather than to abstract logic or a designer's intuition. The principle, traceable to E. Wyndham Hulme's 1911 idea that classification should be warranted by the books that exist, was given an empirical, corpus-based operationalization by Clare Beghtol in her study of fiction studies, where she used subject descriptors in a bibliographic database to quantify how strongly the domain's literature supported particular concepts and where the field reached consensus. Within Hjørland and Albrechtsen's domain-analysis programme, literary warrant is the empirical anchor that ties a classification or thesaurus to the discourse it serves. The analysis assembles a representative corpus, extracts and counts concepts, measures their warrant, gauges consensus, and lets that evidence determine what the system should contain and how finely it should distinguish.	Domain analysis is the socio-cognitive research programme proposed by Birger Hjørland and Hanne Albrechtsen in 1995, which holds that the most fruitful object of study for information science is the knowledge domain understood as a discourse or thought community within society's division of labour. Rather than grounding information organization in the isolated mental processes of an individual user, domain analysis grounds it in the shared literature, paradigms, terminology, and social practices of a subject field. Hjørland and Albrechtsen set out eleven complementary approaches — from producing literature guides and special classifications to bibliometric, historical, and epistemological study — and Clare Beghtol's work on literary warrant and consensus showed how a domain's own published discourse supplies the empirical basis for its categories. The method turns the design of classifications, thesauri, and retrieval systems into an evidence-based study of how a community actually thinks and writes.
