Plaintiff Williams & Wilkins Company, a medical publisher, charges that the Department of Health, Education, and Welfare, through the National Institutes of Health (NIH) and the National Library of Medicine (NLM), has infringed plaintiff's copyrights in certain of its medical journals by making unauthorized photocopies of articles from those periodicals. Modern photocopying in its relation to copyright spins off troublesome problems, which have been much discussed. Those issues have never before been mooted or determined by a court. In this case, an extensive trial was held before former Trial Judge James F. Davis who decided that the Government was liable for infringement. On review, helped by the briefs and agreements of the parties and the amici curiae, the U.S. Court of Claims takes the other position and holds the United States free of liability in the particular situation presented by this record.
