The advancement of meta-searching of electronic resources (e-resources) has now become possible with the help of gateway, a communications network technology, resulting in greater control over the resources presentation to the users. This paper describes the importance of gateway in managing the e-resources in college's library system. This paper also highlights the objectives, scope and interdisciplinary relevance of gateway in academic libraries. The paper explains the steps involved in building gateway, such as preliminary preparation, planning and designing, development of online gateway, testing and implementation. Besides this, open archive initiative and protocol metadata initiatives (OAI-PMH) and Z39.50 standards, architecture and features of the knowledge gateway have been discussed in this paper.
