Theses and Dissertations are the most valuable scholarly resources that involve the collaborative work of researchers, supervisors, experts, and others. These are the results of at least three years of scientific work accomplished within a laboratory, through a research team, institute, or a university.
The Online Dictionary for Library & Information Science (ODLIS) defines Electronic Theses and Dissertations (ETD) as "The Master's theses and Ph.D. dissertations submitted in digital form rather than in print on paper, as opposed to those submitted in hard copy and subsequently converted to a machine-readable format."
ETDs are transforming the scholarly communication landscape through knowledge creation and sharing for industrialization and modernization.
ETD repositories have become platforms for the intellectual achievements of scholars and their institutions by making their research output available globally. It provides easy & wider access to theses and dissertations. To enable the researchers to access ETD contents from a single point, many institutional, national and international networks and organizations have taken initiatives to establish ETD repositories.
