"In conception, scope and detail, this catalogue is outstanding. The entries are intelligently structured, carefully executed, and present an extraordinary amount of information."--James A. Marrow, University of California, Berkeley "This is one of the finest catalogues of an American collection of manuscripts and a reference work of lasting value. Its publication has been anticipated with the greatest excitement by scholars in a broad range of historical disciplines due to the rich and varied character of the collection."--Thomas Kren, Curator of Manuscripts, The J. Paul Getty Museum
