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.

Wilson�s renown controlled indexing provides precise access to the users� topics:

example:

Shakespeare (thousands of hits)

Shakespeare/Bibliography (+/- 40 hits)

Shakespeare/Bibliography/Editions (8 hits)
