104 LRTS 56(2) Notes on Operations Integration of a Research Management System and an OAI-PMH Compatible ETDs Repository at the University of Novi Sad, Republic of Serbia Lidija Ivanović, Dragan Ivanović, and Dušan Surla This paper discusses the extension of the Current Research Information System (CRIS) at the University of Novi Sad, Republic of Serbia, to incorporate elec- tronic theses and dissertations (ETDs). Data describing ETDs is entered using a web application that enables researchers to input their own data through a webpage without knowing the standards on which the system is based. The ETDs repository can exchange data with CRIS institutional repositories and Networked Digital Library of Theses and Dissertations members. In this way, the interna- tional visibility of theses and dissertations created at the University of Novi Sad is enhanced without duplicating data entry in various systems. This approach has been verified and tested on a dataset of theses and dissertations at the University of Novi Sad. ublic access to theses and dissertations via the Internet is important for the P development of a knowledge-based society. A knowledge-based society relies on the knowledge of its citizens to drive entrepreneurship, innovation, and vitality of that society’s economy. A knowledge-based society possesses a community of scholars, researchers, research networks, engineers, technicians, and businesses engaged in research and the production of high-technology goods and provision Lidija Ivanović ([email protected]. ac.rs) is a teaching assistant, Faculty of of services.
