The development of computer and network technology has led to great changes in the
field of information science. With the development of World Wide Web technology, the
distribution, searching and browsing of information has led to revolutionary changes.
Digital libraries calls for resource sharing, which is a convenient way for managing and
distributing information among users. Heterogeneous systems have to be interconnected
so that the user community can have seamless/precise flow of information as per need.
Also, future systems and services must be interoperable so that there is no potential loss
of precision or data in the data exchange. This paper is an attempt to study
interconnection and interoperability of information systems. Keeping in view the future
users requirements, new technologies in the next generation information systems are also discussed. It is essential that in future networks must be interconnected, the service
must be interoperable and information must be shared.
