To find articles from a specific journal, choose the "Database and Journal Finder" tab from the main search box on the library homepage. In the second box, type in the title of your journal and press search.
On the catalog page, choose one of the database links to go to your journal. Pay special attention to the dates of coverage at each link.
Use the search boxes on the journal pages to search for topics you're interested in. Make sure that you are searching just in your journal, not in the whole database.
