Just as St. Thomas has an institutional repository to post our student dissertations (USTRO), other colleges and universities publish their theses and dissertations in their own. These can be found via Google.
While written specific to journal article authors, APA Style Journal Article Reporting Standards (JARS) are a set of guidelines that can be used to understand what goes in each chapter of your dissertation. Select the corresponding methodology of your dissertation below.
We also have these books describing how to meet the JARS standards.
