As part of the celebration of the U.S. Government Printing Office's 150th anniversary on March 4, 2011, GPO has published a facsimile edition of 100 GPO Years, originally issued in 1961 on its 100th anniversary. "100 GPO Years" takes a chronological approach to GPO history, beginning with a history of public printing in the United States prior to 1860 and describing events year by year from 1861 to 1961. A section of rare photographs illustrates the progress of “the big shop” from handset type to computer typesetting. This reprint edition includes an index, a new foreword, and a new colophon about the type fonts and changing printing technology.
