These techniques included full-text processing; hash codes; Key Word in Context indexing (see also Herbert Marvin Ohlman); auto-indexing; automatic abstracting and the concept of selective dissemination of information (SDI).
Donald Knuth notes that Hans Peter Luhn of IBM appears to have been the first to use the concept, in a memo dated January 1953, and that Robert Morris used the term in a survey paper in CACM which elevated the term from technical jargon to formal terminology.
At the same time, Hans Peter Luhn (working with IBM) distributed his paper titled "Bibliography and index: Literature on information retrieval and machine translation", which contained "titles indexed by Key Words-in-Context system", or KWIC.
