This booklet is an attempt to provide librarians with a short summary of the arguments in favor of library photocopying, combined with a status report on how these arguments have fared in the courts and in the United States Congress. Following an analysis of the issues involved, the case of Williams and Wilkins v. the United States is discussed, with a presentation of the arguments of the American Library Association, the Association of Research Libraries, and the National Library of Medicine followed by the reactions of the library community. Part 2 of the booklet reviews congressional action on copyright and includes the photocopying provisions of Senate Bill 1361. (Author/SL)
