SearchWorks Articles + is particularly good for finding articles where you already know the citation.
You can search for an known article by title (using quotes is more efficient). Type the title of the article in the search box. You can select "Article title" from the search options. You can also choose to search "all fields" and put more information, such as author and journal title.
