DIFFERENT TYPES OF INFORMATION SERVICES:
Modem libraries and information centres provide a variety of documentation and information services to support research and development, industrial productivity, management, marketing and trade activities and all other programmes of development of government and non-governmental institutions. There has been a tremendous increase in the volume and variety of such services and products. As has been stated earlier, the information services provided may be categorised into anticipatory and responsive services. Since there are separate Units which would be describing and discussing Reference Services, Current Awareness Services, Literature Search and Database Services, this Unit will provide only a brief account of some of these services emphasising some generic aspects as an overview.
