It's best to use larger index databases that may not deliver full-text, but give broader coverage.  Most journal databases will give you the option to use the "Get it at Duke" button to locate the hardcopy.

More than half of all art journals are not full text.  Image copyright often prevents previously-published articles from broader, web distribution.  Searching journal titles in the online (Duke) catalog will A) link you to full-text versions or B) tell you where the hard copy runs are (usually Lilly).

When searching for books, it's best to search the entire range of books, not just those held at Duke.  Use Worldcat (tab above, "Catalogs").  Just about any book in Worldcat can be obtained through interlibrary loan.  The trick is to start early with your requests.  Duke has no control over how long another library takes to send your books.  Usually, it's 1-2 weeks.
