When searching for articles in library databases, you can limit your search to only scholarly journals. The screenshots of the databases shown below outline where you can limit by source type to find the type of article you need. Remember that academic articles and scholarly articles are the same thing; different databases use the different terms but you can know that they are the same!

Limiting in this database is very similar to other advanced searches in the library's databases. You can click to limit to full-text articles, to peer-reviewed articles, and you can use the built in Boolean tools (AND, OR, NOT) to change your search results and combine your simple keywords.
