Review articles (or literature reviews) are a great way to get an overview of a research area, with many references to scholarly and research articles. Review articles undergo peer-review and thus qualify as scholarly articles.
The Annual Review journals are a good source of review articles. Web of Science (see middle column) is also good: do your search and then limit your results to reviews on the left side.
To look for articles in journals, newspapers, or magazines, you will need to start with a database. A database will allow you to look by subject or a few keywords which describe your topic or by author.
