The Everett D. Graff Collection of Western Americana consists of some 10,000 books, manuscripts, maps, pamphlets, broadsides, broadsheets, and photographs, of which about half are described in the present catalogue. The Graff Collection displays the remarkable breadth of interest, knowledge, and taste of a great bibliophile and student of Western American history. From this rich collection, now in The Newberry Library, Chicago, its former Curator, Colton Storm, has compiled a discriminating and representative Catalogue of the rarer and more unusual materials. Collectors, bibliographers, librarians, historians, and book dealers specializing in Americana will find the Graff Catalogue an interesting and essential tool. Detailed collations and binding descriptions are cited, and many of the more important works have been annotated by Mr. Graff and Mr. Storm. An extensive index of persons and subjects makes the book useful to the scholar as well as to the collector and dealer. The book is not a bibliography but rather a guide to rare or unique source materials now enriching The Newberry Library's outstanding holdings in American history.
