Databases can contain links to the text of the articles they contain. If not:
Look for the "link to full text" option. This may look different in different databases, but it's there in most every indexing database. If a recent year, we may have the item in print in the Library.
If you know which specific periodical, consult LMU's Journal List (on the Library homepage) to determine if the Library owns the article you need. This List tells you if the journal is available in print or in one of our online databases.
