If you're looking for a specific item, the easiest way to track it down is by using the library catalogue, iDiscover. Type a few words from the article's title into the search box. If the article is available online (and many of them are) then you should be able to get to it directly by clicking 'Full text available'. If it isn't online, then iDiscover will tell you where copies of the print journal can be found.
