In order to be in accordance with current copyright laws, the Library of Congress limits most of its e-book offerings to works first published in America before 1923. However, the Library includes more recent public domain documents generated by the federal government or the Library itself, such as annual reports, illustrated collection guides, Federal Research Division country studies, and a history of the Library of Congress.
See the United States Copyright Office Web site for more information on copyright or to search the Copyright Catalog to check on an item’s copyright status. Consult the Library's guide for additional resources on searching copyright registration and renewal records.
The Library of Congress Web site has details about the National Library Service for the Blind and Physically Handicapped, which makes Braille and audio materials available by mail to eligible borrowers in the United States.
