The role of Harold Lasswell Communication Theory in Librarianship and Information Science

Abstract

Communication is a process. In this process or activity, various components are involved in a variable environment. To further understand the process of communication, from the past, scientists analyzed the communication situations into its constituent elements and designed and introduced models such as: Aristotle's Model, Indiana, Shannon, and Weaver, Wilber Sharam and Harold Lasswell, and etc. Communication models indicate the nature and mode of communication. The initial models were very simple and by considerable effort and research, they became more complex. All models have three basic elements: sender who sends a message for a particular purpose. The message is transmitted for a goal and transfers special concept, and the receiver is successful when a complete understanding of the sender‟s message occurs. In this study, one of these models i.e. Harold Lasswell's model (Lasswell's Communication Theory), has been investigated, and by describing definitions and concepts related to the field of communication, information and the overlapping of information and communication, the role of Harold Lasswell communications theory in librarianship and information science has been investigated
