This book is meant as a successor to the bibliography of the Hudson River School in Bernard Karpel's Arts in America: A Bibliography, Vol. Two (Archives of American Art, 1979). Its purpose is twofold: to fill some of the gaps that Karpel was forced to leave unfilled; and to record the great activity in Hudson River School studies that has taken place in the decade since the publication of Arts in America. Sullivan includes Albert Bierstadt, Frederic E. Church, Thomas Cole, Jasper F. Cropsey, Thomas Doughty, Asher B. Durand, Sanford R. Gifford, Martin J. Heade, George Inness, John F. Kensett, Fitz Hugh Lane, Homer D. Martin, Thomas Moran, Worthington Whittredge, Alexander H. Wyant, and others.
