If you are in any Ebsco database, you can limit to just scholarly/peer reviewed journal articles.
After you conduct your search you will have the option to "Refine Results on the left hand side of the page. One of the options you can click is "Scholarly/Peer Reviewed". This will get rid of all newspapers, trade journals, magazines, etc.
You can also change the time frame for the articles if you want to use the most recent materials. Simply slide the bar to match the year range you are looking into.
