Our article databases include options to search by title - just look for a way (usually found on a drop-down menu near the search box) to select this field.
If you have the complete article citation, or at least know the name of the journal in which the article appeared and the title, you may want to start by searching the E-Journal Portal for the journal. This is how you'll know which database(s) include the journal in which your article appeared, and then you can search by title within that content.
As always, if you have any questions or need help finding a specific article, you are encouraged to ask a librarian.
