If your search is not successful, always double check the spelling before assuming the library owns nothing by this author. First you type in your author, last name first, then you will be prompted to type in words from the title you wish to find by that author. Subject Headings are used. If the term entered is not an LC Subject Heading, you will see an alphabetical list of subject headings closest to the subject heading you enter or a cross reference to a an LC Subject Heading. This finds items with both words Arizona and geology, as well as items with all 3 words New and Mexico and geology.
Truncation is automatic only for some search types.
Sometimes automatic truncation results in too many irrelevant answers. Follow menu instructions to build your search request.
