The library professionals in recent times have experienced tremendous transformation of available library resources and services. In Indian perspective the IITs (Indian Institute of Technology) are the premier institutions and their libraries are redesigned to have the online availability of quality information resources and services such as e-journals, e-prints, databases, library catalogues (OPAC, Web OPAG), education materials, information on organizations, associations and so on. Web technologies offer a platform to these institutions to make available all informational resources to their patrons via websites or WebPages. In this research paper a study has been done on the Libraries of IITs with an aim to evaluate their web-based informational resources, services, websites/OPACs and to further study what measures they have taken to better represent web based informational resources and services to their clienteles. 收起
