2.4. FUNCTIONS OF DEPOSITORY
LIBRARIES IN THE UNITED STATES
The Superintendent of Documents, United
States Government Printing Office, is author-
ized by law to furnish Government publica-
tions to designated depository libraries.

Under provisions of Title 44 of the United
States Code, certain libraries are designated
depositories for Government publications.
Through them, Federal Government documents
are made available to residents of every State,
District of Columbia, Guam, Puerto Rico, and
the Virgin Islands. Distribution to the libraries
is made by the Office of the Superintendent of
Documents.

It is sometimes impossible to obtain desired
publications by purchase from the Superin-
tendent of Documents. Stocks may have been
exhausted or the document may be permanent-
ly out of print. In these instances the deposi-
tories render an invaluable service by keeping
such publications permanently available. Every
Government publication cannot be consulted
at all depository libraries. Designated
Regional Depositories are required to receive

and retain one copy of all Government publica-
tions made available to depository libraries
either in printed or microfacsimile form. All
other libraries are allowed to select the classes
of publications best suited to the interest of
their particular clientele.

These libraries are now receiving selected
publication series of the National Bureau of
Standards for general reference use. Whether
a given library has a copy of a particular publi-
cation can be determined by inquiring at the
library.

2.5. FUNCTIONS OF U.S. DEPARTMENT
OF COMMERCE DISTRICT OFFICES

provide ready access, at the local level, to the
services of the Department of Commerce as well
as to its reports, publications, statistical state-
ments, and surveys. Each District Office serves
as an official sales agent of the Superintendent
of Documents, U.S. Government Printing Office,
making available for purchase locally a wide
range of Government publications. The refer-
ence library maintained by each District Office
contains many Government and private publica-
tions, periodicals, directories, reports, and other
reference materials.

can be consulted at libraries. Also, in many

tion concerning this service, write to the Photo-
duplication Service, Library of Congress, Wash-
ington, DC 20540.
