Once you find the citation, try the   button to see if Penn State has the electronic or print version of the article you need. If the electronic version is available, it will appear as the first link on the Get it! menu. If the article is not available electronically, click on The CAT link to automatically search our catalog and see if Penn State has a print copy. If no other copy is available, you use the InterLibrary Loan (ILL) link to request it from another library.  ILL will get a copy of the article for you, typically at no cost; articles usually arrive within a week, often in as few as 2-3 days. Watch your PSU email for notification and further instructions.
