Information and communication technology has a great influence on scientific communication and work of scientists. Ways in which research is conducted have changed; science has become more highly collaborative; network-based, and data-intensive. The existing system of scientific publishing is experiencing pressure for change under the influence of the exponential growth of information production, the dramatic increase in subscription fees, the increasing storage cost of printed documents, and the increasing power and availability of digital technology.
To conduct their research more effectively scientists need modern resources of digital information which would support their endeavor. Digital repository is one such type of information resources. Digital repository is an institutional digital archive of the intellectual product created by the faculty, research staff, and students of an institution and accessible to end users both within and outside of the institution.
Digital repositories carry a great potential for the advancement of scientific research. Digital repositories can store different file formats and types of content. An institutional digital repository can contain e-prints of scientific papers, research data, but also e-learning materials and other forms of institutional intellectual outputs. As the number of open access digital repositories grows, it has become evident that institutional repositories are now clearly and broadly being recognized as essential infrastructure for scholarship in the digital world.
