The Frick Art Reference Library was established in 1920 by Helen Clay Frick, daughter of Henry Clay Frick, founder of the adjacent museum. Each year the Library serves approximately six thousand individuals with a serious interest in art, primarily scholars, museum and art market professionals, collectors, and graduate students. One of the world’s most valued art research centers for the study of art in the Western tradition, it is also one of the most complete resources for the study of collecting and patronage.
