Institutional Repositories (IRs) are an effective way of managing and disseminating institutions’ in scholarly communication. More specifically, an IR enhances the visibility and discoverability of the content and validates the repository’s importance. Knowledge Organisation System (KOS) strengthens the digital content organisation, connects users with collections, and improves information retrieval functionalities. This paper investigates the present status of user interface features and incorporates KOS in the institutional repository of technical institutions, restricted to Centrally Funded Technical Institutions in India. A group of twenty-four web-accessible institutional repositories was identified, and their KOS and user interface features were evaluated. It was found that user interfaces of all IRs under study comply with essential search and navigation functionalities, such as simple and advanced search, browsing, faceted or filtering approaches, and integration with multiple KOS. Only a few of them include complex KOS, such as control vocabulary. All repositories show their search results in both normal-text and metadata views. Some have specific display features, such as highlighting the query or displaying a thumbnail. Google is one of the most popular search engines that indexes IR content for visibility and discoverability, and approximately 90 per cent of repositories are linked with NDLI. Global visibility and impact participation are moderate, and they require attention. [ABSTRACT FROM AUTHOR]

Every institution needs repositories for storing, organizing, and presenting digital content, as well as maintaining digital resources for long-term digital access. The authors discussed India's OpenDOAR status, a quality-assured listing of open-access repositories globally, with a particular emphasis on the Shodhganga repository. The focus of this paper is on universities in Northeast India that deposit Electronic Theses and Dissertations (ETDs) in the Shodhganga repository. This study depicts repositories in India since their inception. The Northeastern states are given special treatment by the Central Government and INFLIBNET in the form of Planners (Promotion of Library Automation and Networking in North Eastern Region). The study's main goals are to disclose the knowledge outcome as well as the knowledge gap that exists in this geographical location. The study helps determine the number of universities in Northeast India that follow the "University Grants Commission (UGC) Minimum Standards & Procedure for Award of M.Phil. / Ph.D. Degree, Regulation, 2009," which mandated that electronic version of Theses be uploaded to the Shodhganga repository for the benefit of scholars across the country.

The information and communication technology has given various ways of storing and providing scientific information to the libraries. A digital collection maintained by the university or an academic institution to capture and preserve the intellectual output of its staff and faculty members is called as an institutional repository (IR). The concept of maintaining the IR by academic libraries for the information created by an institution in the form of conference articles, journal articles, audio-video lectures, educational powerpoint presentations, books, patents, etc., is one such way to provide the institutional scientific information openly (with some restriction for the copyrighted articles). The IR has been given a new role to the librarians to be a part of creation of information apart from storing and dissemination of information. Manipal Usniversity (MU) has used EPrints open source software to maintain its IR. This paper describes the elaborative study on Manipal University Digital Repository (MUDR) and its collection growth. Some suggestions that can be implemented to improve the strength and visibility of MUDR are presented, which can be equally applicable to any institutional repository. [ABSTRACT FROM AUTHOR]
