The NIO library has been recognised as the National Information Centre for Marine Sciences (NICMAS) since mid 90s. While catering to the needs of the users from within the institute, it is also committed to serve the marine information seekers within and outside India.

Most of the operations in the library have been computerised and it uses ISIS based softwares at backend. The electronic resources are open to the institute staff on the Intranet library server.

The library is open from 09:00 - 13:15 and 13:45 - 17:30 hrs on all working days.

The information and facilites made available over here are basically meant for the users outside the institute.
