Newspapers are only available by using the "Newspapers" section of Primo. This is a separate index that contains, exclusively: newspaper articles, magazine articles, and other news items such as press releases. Recent and historical publications are included. These records are not mixed in with results from other Primo searches.
You can access the Newspaper Search feature from the menu under "Resource Type" of the Primo results page. You can also link directly to Newspaper Search from Primo's main navigation menu on the top of your screen.
