As you are clarifying your chosen dissertation topic, be sure to read other dissertations about your general topic area. This helps you accomplish two things. First, you better understand the questions being asked and research being completed in your topic area, which can help you define your questions and refine your research methodology. Second, you begin to develop a stronger understanding of the structural foundations of a dissertation and how it comes together. The more you know about other dissertations, the easier it will be to complete yours.
