Reviewing doctoral dissertations is a very effective way to engage in the study of an interest. Chapter Two of most dissertations will give you an excellent collection of the best literature in the field, as well as many of the research pieces of a given topic. Chapter Four will generally report the findings of the dissertation research, and Chapter Five will make recommendations, tease out implications, and summarize ways in which the dissertation you are reading is related to previous research.
Welcome to the wonderful world of doctoral research!
