Until recently theses and dissertations (Masters and Doctoral) were only available in printed form. Now, worldwide, institutions are digitising their collections putting pdf copies into the public arena. Theses can be traced via Google, GoogleScholar or from a particular institution's theses repositories, usually from the Library's webpage.
