Report of the Register of Copyrights on the General Revision of U.S. Copyright Law… (1961)
“ Thus, when a researcher wants the whole of a publication, and a publisher's copy is available, he should be expected to procure such a copy. In situations where it would not be likely to compete with the publisher's market, however, we believe that a library should be permitted to supply a single photocopy of material in its collections for use in research. Thus, when a researcher wants only a relatively small part of a publication, or when the work is out of print, supplying him with a single photocopy would not seriously prejudice the interests of the copyright owner. ”
