Top recommendations -- be sure to use more than one!
Use "Journal Finder" - either the link near the article citation, or on the Library's home page. Just type in the journal name and check for the date you need.
If there are no results -
Use ILL@CNU, the Interlibrary Loan system to request the article you need
Check for holdings at other local libraries, and take your VTC card and go get the article yourself.
If what you need is not here at CNU, use ILL@CNU, the Interlibrary Loan service.
Remember to check your CNU email for ILL arrivals.
