posters; government documents, newspapers, and periodicals from all over the world; and motion pictures, microforms, and audio and video tapes. Reference Resources Admission to the various research facilities of the Library is free. No introduction or credentials are required for persons over high school age who wish to read in the general reading rooms; however, certain collections, like those of the Manuscript, Rare Book and Special Collections, and Motion Picture, Broadcasting and Recorded Sound Divisions, can be used only by those with a serious purpose for doing so. As demands for service to Congress and Federal Goverment agencies permit, limited reference service is available through correspondence. The Library must, however, decline some requests with the suggestion that a library within the correspondent's area can provide satisfactory assistance. While priority is given to inquiries pertaining to its holdings of special materials or to subjects in which its resources are unique, the Library does attempt to provide helpful responses to all inquirers. Copyrights Since 1870 the Library has been responsible for copyrights, which are now registered by the Copyright Office (acts of July 8, 1870 (16 Stat. 212-217), February 19, 1897 (29 Stat. 545), March 4, 1909, as codified and amended, and October 19, 1976 (90 Stat. 2541)). All copyrightable works, whether published or unpublished, are subject to a system of statutory protection that gives the copyright owner certain exclusive rights, including the right to reproduce the copyrighted work and distribute it to the public by sale, rental, lease, or lending. Works of authorship include books, periodicals, and other literary works, musical compositions, song lyrics, dramas and dramatico-musical compositions, pictorial, graphic, and sculptural works, pantomimes and choreographic works, motion pictures and other audiovisual works, and sound recordings. Extension of Service The Library extends its service through:

-an interlibrary loan system;

-the photoduplication, at reasonable cost, of books, manuscripts, maps, newspapers, and prints in its collections;

-the sale of sound recordings, which are released by its Recording Laboratory; -the exchange of duplicates with other institutions;

-the sale of printed catalog cards and magnetic tapes and the publication in book format or microform of cumulative catalogs, which make available the results of the expert bibliographical and cataloging work of its technical personnel;

-a centralized cataloging program whereby the Library of Congress acquires material published all over the world, catalogs it promptly, and distributes cataloging information in machinereadable form as well as by printed cards and other means to the Nation's libraries; -a cooperative cataloging program whereby the cataloging of data, by name authority and bibliographic records, prepared by other libraries becomes part of the Library of Congress data base and is distributed through the MARC Distribution Service;

-a cataloging-in-publication program in cooperation with American publishers for printing cataloging information in current books;

-the National Serials Data Program, a national center that maintains a record of serial titles to which International Standard Serial Numbers have been assigned and serves, with this file, as the United States Register; and

-the development of general schemes of classification (Library of Congress and Dewey Decimal), subject headings, and cataloging, embracing the entire field of printed matter.

Furthermore, the Library provides for: -the preparation of bibliographical lists responsive to the needs of Government and research;

-the maintenance and the publication of The National Union Catalogs and other cooperative publications;

-the publication of catalogs, bibliographical guides, and lists, and of texts of original manuscripts and rare books in the Library of Congress;

-the circulation in traveling exhibits of
items from the Library's collections; and
-the provision of books in raised type
and "talking book" records, as well as
books on tape, for the blind and the
physically handicapped through 159
cooperating libraries throughout the
United States.

American Folklife Center The Center,
which was established in the Library of
Congress by act of January 2, 1976 (20
U.S.C. 2102 et seq.), has a coordinative
function both in and outside the Federal
Establishment to carry out appropriate
programs to support, preserve, and
present American folklife through such
activities as the collection and
maintenance of archives, scholarly
research, field projects, performances,
exhibitions, festivals, workshops,
publications, and audiovisual

presentations. The Center is directed by a
Board of Trustees consisting of four
members appointed by the President
from Federal agencies, four each
appointed by the President pro tempore
of the Senate and the Speaker of the
House from private life, and five ex
officio members: the Librarian of
Congress, the Secretary of the
Smithsonian Institution, the Chairmen of
the National Endowment for the Arts and
the National Endowment for the
Humanities, and the Director of the
Center.

The Center has conducted a number
of projects in many locations across the
country, such as the ethnic communities
of Chicago, IL; southern Georgia; a
ranching community in northern Nevada;
the Blue Ridge Parkway in southern
Virginia and northern North Carolina;
and the States of Rhode Island and
Montana. The projects have provided
large collections of recordings and
photographs, which are being
incorporated into the Library's
collections. The Center administers the
Federal Cylinder Project, which is
charged with preserving and
disseminating music and oral traditions
recorded on wax cylinders dating from
the late 1800's to the early 1940's. The
Cultural Conservation Study was
developed at the Center, in cooperation

with the Department of the Interior,
pursuant to a congressional mandate.
Various conferences, workshops, and
symposia are given throughout the year.
A series of outdoor concerts of
traditional music are scheduled monthly
at the Library, April through September.
The Folklife Center News, a quarterly
newsletter, and other informational
publications are available upon request.
The Government Printing Office sells
additional Center publications, including
the Folklife Annual and catalogs
produced by the Federal Cylinder
Project.

Archive of Folk Culture, a subdivision
of the American Folklife Center,
maintains and administers an extensive
collection of folk music and lore in
published and unpublished forms. It is a
national repository for folk-related
recordings, manuscripts, and other
materials. The Archive's reading room
contains over 3,500 books and
periodicals; a sizable collection of
magazines, newsletters, unpublished
theses, and dissertations; field notes; and
many textual and some musical
transcriptions and recordings.

For further information, call 202-287-6590.
Center for the Book The Center was
established in the Library of Congress by
act of October 17, 1977 (2 U.S.C. 171
et seq.), to provide a program for
investigating the transmission of human
knowledge and to heighten public
interest in the role of books and printing
in the diffusion of knowledge. Drawing
on the resources of the Library of
Congress, the Center works closely with
other organizations to explore important
issues in the book and educational
communities, to encourage reading, and
to encourage research about books and
about reading. Its goal is to serve as a
useful catalyst by bringing together
authors, publishers, librarians,
booksellers, educators, scholars, and
readers to discuss common concerns and
work toward the solution of common
problems.

Except for basic administrative support
provided by the Library of Congress, the
Center and its activities are privately

funded. Over 130 citizens serve on its
National Advisory Board. Three
committees reflect its primary concerns:
the book in contemporary society,
nationally and internationally; reading
and book promotion; and the history of
books. Major Center for the Book
conferences have dealt with "Television,
the Book, and the Classroom," "Reading
in America," "The Textbook in American
Education," and "Public Lending Rights."
For further information, call 202-287-5221.
