Libraries in India are striving to provide necessary and relevant information to their users. Limited resources have been one main barrier to satisfying the growing informational needs of the users. Now, the Indian libraries are planning various methods of resource sharing to help meet information demands. Attitudes of library and institutional managements have undergone a change, to become more open to the benefits of resource sharing. A number of formal arrangements are being made for resource sharing among the libraries. A number of resource-sharing activities are discussed in this article, broadly arranged under four headings: National Information System in Science and Technology (NISSAT) National Information Centres (NIC); library consortia; document delivery services; and interlibrary cooperation.
