A great place to start is the Search All Resources box in the middle of the library's webpage.
Type in "twelve step programs" substance and click in the box next to Scholarly (Peer-Reviewed). Then click the orange Search button.
The results list will include articles from scholarly, peer-reviewed journals published from 1997 to the present. If you would like to only see articles published in the last five years, go to All filters. Click on the drop-down menu for Date Range and select the time range you would like. Select Apply filters to narrow the results.
