When searching for a journal article use keywords from the article title not the journal title.
For example, if you were looking for this journal article:
Beyes, T. (2010) ‘Uncontained: The art and politics of reconfiguring urban space’, Culture and Organization, 16 (3), pp. 229-246.
You could do a search using the author’s name, Beyes, and keywords from the article title e.g. “uncontained”, “art” and “politics”. DiscoverEd will look for items that include all the keywords in the item record.
