It is important to select the correct collection or library of materials by choosing the relevant collection on the main page. The basic search box provides tabs for searching 'Full Text', 'Citation', 'Catalog', or 'Case Law'. If you are searching for a known citation or title, the basic search option is likely to be adequate. For more complex searches, especially for full text searches, browsing the collection or using the advanced search option may be more useful.
