You can find peer-reviewed, scholarly, trade, newspaper, and magazine articles in the CSU Library through the Discovery Search box on the library homepage or by clicking on any of the databases linked within the Databases box.
If you are looking for peer-reviewed articles, you can use the peer-reviewed filters to limit to only peer-reviewed articles.
In most databases on both the Advanced Search page and the Results page there is a place to limit by article type or source/resource type, where you can limit to different types of sources.
