For Unique and Timely Topics, Consider Dissertations & Theses
Benefits of using dissertations or theses:
For a comprehensive/exhaustive literature review:
See what has been done recently--find and review dissertations or theses on your topic to get ideas for future research.
When reviewing these works, review the literature review, methodology, or surveys (often includes full-text of instruments/questionnaires) and the references list.
CAVEAT: Dissertations are not considered peer-reviewed.
Dissertation: "A lengthy, formal written treatise or thesis, especially an account of scholarly investigation or original research on a specialized topic, submitted to a university in partial fulfillment of the requirements for a Ph.D. degree."
Thesis (Theses, plural): "A proposition advanced and defended in a formal disputation, especially by a candidate in partial fulfillment of university requirements for a master's degree."
