Abstract

Reviews the literature of the information chain analogous to ecology's food chain, taking the Royal Scientific Information Conference 1948 as the seminal point. Describes 8 successive models of the information chain each incorporating contemporary thoughts and experiences. Each model is labelled with the year to which it may be said to refer: Distribution of Scientific Information 1948; Document Network 1967; Dissemination of scientific and technical information 1978; Structure of Scientific Literature 1979; Ecosystem of scientific communication 1980; Information Chain 1988; Information Chain 1989; Pathways of N formation Flow 1993. Although of wide applicability the focus of interest for information scientists tends to be the communication of learned information
