USE THE * [asterisk symbol]: ROOT WORD AND SPELLING VARIATIONS
TO COMBINE LIKE TERMS TOGETHER: use OR
"John La Farge" or Thomas Couture
TO COMBINE DIFFERENT CONCEPTS: use AND
america* AND paint* AND "John La Farge"
TO USE BOTH METHODS FOR A SMART SEARCH:
AUTHOR: In the library catalogs, works of authorship for artists can include art exhibition catalogs, books where the main focus in on publishing art reproductions of the artists, as well as textual or literary works of authorship by an artists (essays, lectures, letters, etc.). These include primary resources.
SUBJECT: Works primarily about an artist (monographs, scholarship about an artist, etc.) are classified by subject.
When you search by author you will get a different subset of material than if you search by subject! Try both approaches, or use keyword or phrase searching, e.g. "John La Farge" when looking in the library catalog.
