Q. How do I find articles on a topic? Do you have step-by-step instructions?

I would use ProQuest and EBSCO. Here are instructions for both:

Journal Articles - EBSCO Database (Scholarly journals, magazines, newspapers)
Click on the Find an Article tab.
Select EBSCO; this will take you to the EBSCO login page.
To login enter your SLU username [first name.last name] and the password that you use for your SLU email.
Select All EBSCOhost Reference Databases.
Check the boxes next to Academic Search Complete and any other databases that seem relevant to your topic.
Click on the Continue button at the bottom of the page.
Click on Advanced Search under the basic search box.
Scroll down the page and check the boxes Full-Text (complete articles) and Scholarly, Peer-Reviewed (if required – this will significantly limit your results).
Enter your search terms in two or more search boxes, separated by AND, OR, or NOT and click on Search.
Click on the “PDF Full Text” or “HTML” icons to view the article.
If you don't get the results you're looking for, or too many, try other relevant terms.
Use the options in the Refine Menu on the left to narrow down your results.

Journal Articles – ProQuest Database (Scholarly journals, magazines, newspapers – NYT, WSJ)
Click the Find an Article tab
Select ProQuest; this will take you to the ProQuest login page.
To login enter your SLU username [first name.last name] and the password that you use for your SLU email
You should now be on the Advanced Search page (if not, click on “Advanced Search.”).
Check the boxes for Full Text (complete articles) and Peer Reviewed (if required).
Enter your search terms in two or more search boxes, separated by AND, OR, or NOT and click on Search.
Click on the “Full Text” or “Full Text – PDF” icons to view the article.
If you don't get the results you're looking for, or too many, try other relevant terms.
Use the options in the Narrow Results menu on the left to refine your results.
