Cheracteristics of SDI: The following are the characteristics of SDI service: It is a computerised assisted service. SDI is concerned with current published information. The source of current information may be available both within the organization and outside it. • The new / current information should be disseminated to the users such as researchers, scientists, managers, etc. within the organization. • The channeling or directing of this information depends upon the nature of this interest. • One of the important things in SDI service is that only current and selective information which is highly relevant to the user’s interest is to be selected by the computer for dissemination • •
Objectives of SDI • Some of the objectives of selective dissemination of information (SDI) services are as follows: • To provide current information on a predefined area of interest. • To receive, scan and provide the literature / information to the right users at the right time. • All the current information which is relevant to the interest of the user must be brought to the notice of the user (notification). • All the relevant information which is published elsewhere in the world (in English or other languages) should be located through various sources. • To achieve current requirements through the scan of current material such as journals, current awareness bulletins and other important resources. • To save the time of the user. • No irrelevant documents should be brought to the notice of the user.
