Q. I found a good source, but it's kind of old. How can I find newer articles on this type of research?
Google Scholar has a tool that shows you newer research that cited a book or article.
1. Go to Google Scholar
2. Search for the title of your source
3. Under the text preview, click the "Cited By" link
This will show you all of the sources within Google Scholar that have cited your starting source since it was published. Many of these sources will be on similar topics and will carry the research forward.
Search within these results, as pictured below, to get to the most relevant results.
