The Topics page on the American Sociological Association's website is a great place to start. Choose one or combine several topics to help you brainstorm areas to take your research.
"Through Sociology, we study our behavior as social beings, covering everything from the analysis of short contacts between anonymous individuals on the street to the study of global social processes. ASA Topics web pages provide various lenses through which to explore those studies, their findings and the questions that they trigger."
A library database allows you to search across a number of publications, and the academic journals included in Sociological Abstracts represent the core literature in Sociology.
If you want to look in only one publication, the following links will allow you to search for articles within a specific journal.
