Searching the Literature
In your toolbox of resources, consider how broad versus how specific your searches are. Starting with Google or Google Scholar might be more broad than you need, when an article database might be more specific to your needs. On the other hand, you might want to start very broadly if this is your first time searching the topic. Whatever the case may be, consider that you narrow or broaden your search just by adjusting the place you start your search.
Identify Core Concepts and Keywords
It can be helpful to break down your research question into core concepts and keywords, tied together with Boolean Operators.
