Introduction to United States public documents

the long version

"The purpose of this text is to set forth an introductory account of the basic sources of information that comprise the bibliographic structure of federal government publications. Like the previous editions, the work serves as a reference source for institutions that acquire public documents, as a text for library school students, as a guide for researchers who must access the vast amount of information produced by or for the federal establishment. The emphasis remains a contemporary one; the reader is encouraged to consult other historical or specialized studies for more detailed information."--Pref.
