Sometimes your best option is get to the journal and then search for the article.
Look at the citation. This tells you the name of the journal, the volume and issue number, the date, and the page numbers.
Then open a new tab or window in your browser. You want to keep the citation information available.
Go to Journal Finder.
Search the title of the journal. If you linked to Journal Finder from WorldCat Discovery, first you'll need to go to the Search tab, then select Journals.
You will arrive at the following screen, which shows which providers/databases have this journal, and which dates are covered. Check the date of your article before choosing a link.
Once you link to the journal, you will want to navigate to the volume/issue you need.
For example, my article is from 2009 vol.17 no.2. As I browsed the issues, I noticed something was wrong: the 2009 issues are vol. 21, not vol. 17. My issue is actually from 2005! This is why the WorldCat link failed.
Once you are in the correct issue, look for your page number. For example, my article starts on page 109.
