You can find systematic reviews by looking in several databases that specifically provide indexing for those types of materials.  To find which databases, start at the libraries home page: libraries.uark.edu

Use the drop-down beside the search bar to go to Databases.  Then click on Databases by Title and Subject.

Click on the drop-down menu titled All Database Types, from that menu scroll down until you find Systematic Reviews.

We also have a research guide on Evidence Synthesis that includes tools for finding systematic reviews.
