Links in InformationTransmission Chain:
i) Sources of Generation: As discussed in Unit 1, the researchers and their employing oreganisations are responsible for generating information The outputs are in the form of research papers and reports.
ii) The Primary Publications System: The most important component of this system is the primary journal which publishes outputs of research as research papers. It is mechanism for linking the members of the research community who are working in the same field. A researcher may gather information directly from these primary sources (Journals).
iii) The Secondary/Tertiary Publications Systems: The indexing and abstracting puhlioadooo6eloug to this group. They are aimed at accelerating transmission of information to users, i.e., they link the primary sources to users.
iv) Facilitators of Information Transmission: Although researchers have access to both the primary and secondary publications, they also need intermediaries which can link them to the right sources at the right time. Libraries and information centres act as facilitators of information transmission from the generator to the user and from one user to another.
