When writing a dissertation, the goal of creating original, scholarly research is to add to the body of knowledge. Your first step, therefore, should be to make sure that your proposed study is unique.
You can accomplish this by searching for dissertations similar to your proposed topic in the ProQuest Dissertations & Theses (PQDT) database.
PQDT is the largest single repository of graduate dissertations and theses, with over 3.8 million works from universities worldwide. Use advanced search techniques covered in Searching 101 like subject searching, truncation, and Boolean operators to make your search more precise.
