Figure 1 shows a generic DL infrastructure that contains a user interface and middleware.
The architecture of a generic digital library system (Frew, Freeston, Freitas, Hill, Janee, Lovette, Nideffer, Smith, & Zheng, 1998).
The classic tree-tier architecture: The data engine handles catalog information along with the resources. Additionally, there is a special interface for librarians to manage the content and catalog descriptions. To enable interoperability between library systems a communication interface is defined as well.
The review of literature is an essential component of any investigation, which gives necessary input to the investigator to frame the research study on the chosen topic. As far as the field of “Digital library and the Intellectual Property Rights Issues”, a large number of studies have been conducted and it is continuous to grow. A number of research reports, articles, books and conference volumes on the subject have been published. It is extremely difficult to review the entire body of research. Therefore, some of the contributions in the aspects of DL and IPR issues are reviewed.
