In addition to keyword searching, users can employ limit fields. Limit fields, when combined with other search terms are particularly useful for focusing or limiting a search. For example, students can search Shakespeare and further refine the inquiry by specifing �Bibliography� or �Symposium� as the Document Type. Thus retrieving those articles that include a Bibliography of Shakespeare, or Symposia on Shakespeare.
Searches can also be narrowed by Journal, ISBN/ISSN, Publication year or range of years.

example:
Shakespeare (thousands of hits)
Shakespeare/Bibliography (+/- 40 hits)
Shakespeare/Bibliography/Editions (8 hits)
