Pioneer Imprints From Fifty States will enable readers to view the Library of Congress collections from an unaccustomed angle. It takes for its subject the Library's earliest examples of printing from within present-day boundaries of each State in the Union, providing for each in turn 1) a brief statement about the origin of printing; 2) identification of the Library's earliest examples—among them broadsides, newspapers, individual laws, almanacs, primers, and longer works; and 3) information, if available, about the provenance of these rarities.

Each of the 50 sections may be consulted independently. To those who read it through, however, Pioneer Imprints will give some idea of the movement of printers and presses across the Nation, as well as insight into the nature and history of the Library's holdings.

The author wishes to express his indebtedness to Frederick R. Goff, Chief of the Library of Congress Rare Book Division from 1945 to 1972, who has been constantly helpful and encouraging; to Thomas R. Adams, Librarian of the John Carter Brown Library, Providence, R.I., who read the first 13 sections before their publication under the title "The Library's Earliest Colonial Imprints" in the Quarterly Journal of the Library of Congress for July 1967; and to Marcus A. McCorison, Director and Librarian of the American Antiquarian Society, Worcester, Mass., who read the manuscript of the later sections. These scholars cannot, of course, be held responsible for any errors or faults in this bibliographical investigation. The author's indebtedness to printed sources is revealed to some extent by notes appearing at the end of each section. He is obliged for much of his information to the staffs of the Library of Congress, the National Archives, and the Smithsonian Institution, as well as to the following correspondents: Alfred L. Bush, Curator, Princeton Collections of Western Americana, Princeton University Library; G. Glenn Clift, Assistant Director, Kentucky Historical Society; James H. Dowdy, Archivist, St. Mary's Seminary, Baltimore; Caroline Dunn, Librarian, William Henry Smith Memorial Library, Indianapolis; Joyce Eakin, Librarian, U.S. Army Military History Research Collection, Carlisle Barracks, Pa.; Arthur Perrault, Librarian, Advocates' Library, Montreal; P. W. Filby, Librarian, Maryland Historical Society; Lilla M. Hawes, Director, Georgia Historical Society; Earl E.
