A word of caution: Scholarly journals can contain non-scholarly articles!
For example, many scholarly journals publish book reviews and letters to the editor. These are not peer-reviewed, but they will show up in database search results even if you check the option to receive only results from scholarly/academic journals.
Luckily, you can spot these articles easily. They don't cite their sources formally, they don't have formal sections, and they are often very short. Many databases also label these types of articles to make it easier for you.
