Research on most any topic can be enriched by reading and investigating the scholarly literature. You have access to a rich body of academic writing, including peer-reviewed articles and monographs, through the library databases.
Scholarly articles generally offer an in-depth study of a narrow area of research. Even if you cannot find the "perfect" article that relates to your topic, research on a related area is still valuable and can inform and be incorporated into your own investigation.
As you work on your research journal, consider searching one subject specific library database each week for scholarly articles that address, illuminate, inspire, or otherwise speak to your topic.
