Once you have read through your background information and have identified some keywords and phrases related to your more specific topic, you can begin to look for magazine and journal articles found in library databases.
Use the following examples as a guide for what to type in the Summon search box:
Once you have a list of results, use the options in the side bar to refine your results by date, type of resource, subject, etc.
You might also consider using the tools available to make your search results more manageable. Look for tools that allow you to view only scholarly or academic journal articles, or that allow you to view just the articles that were published in the past few years.
Since Summon doesn't search everything, you may want to look through the complete list of databases.
