In 2007, The Frick Collection and Frick Art Reference Library established the Center for the History of Collecting in America. An important resource for the study of the history of collecting is the collection catalog, which documents items held by an individual, family, or institution at the time of its publication. The Frick Art Reference Library, as well as the other NYARC partners, holds many catalogs related to prominent and not-so-prominent art collections from around the world that are rich with useful information for the researcher piecing together provenance.
