Use the databases listed below to find citations (and sometimes, electronic full text) of journal articles.
To find a particular journal, enter the journal title into the search box of the Journal/Periodical Title Search.
The results will show whether or not the library subscribes to the journal and has the issue that you need, in a print or digital format.
If the article you need is only available in print, you can have a copy emailed to you free through MSU's MARS system.
If MSU does not subscribe to the journal you need, you can request a copy of the article through Inter-Library Loan.
