The theses submitted to universities are a rich and unique source of information on a given topic in terms of breadth as well as depth of treatment and coverage. The insight into the theoretical and methodological foundations of a topic, the data sets, and the exhaustive bibliography-all these attributes make the doctoral thesis a rich resource. A thesis represents the outcome of a focused and extensive study involving intellectual labour of more than three years. Archiving and enhancing access to theses is the main mission of Electronic Theses and Dissertations (ETD) initiatives worldwide. ETDs gracefully overcome many of the problematic issues relating to the archiving and accessing of theses.
