Copyright, Fair Use, and Permission to Copy

• Copyright and Fair Use
• Credits, Copyright, and Permission to Copy

Other material on the Mac Doctor Web Server was taken directly from Internet World Wide Web, Gopher, and FTP servers. To the greatest extent possible we have obtained the explicit permission of the authors or copyright holders. Where we were unable to obtain explicit approval, the selected materials are hereby used under the "fair use" doctrine.

Under the "fair use" doctrine, unauthorized reproduction of copyrighted materials is permissible for such purposes as criticism, comment, news reporting, teaching, scholarship or research. If duplicating a work product is to fall within the bounds of fair use, these four standards must be met for any of the foregoing purposes:

• A. THE PURPOSE AND CHARACTER OF THE USE.
  The use must be for such purposes as teaching or scholarship and must be nonprofit.

  Since the Mac Doctor Web Server is produced and operated on a non-profit basis for use by teachers and their students, this test is met.

• B. THE NATURE OF THE COPYRIGHTED WORK.
  Normal fair use indicates that teachers can make single copies of the following for use in research, instruction or preparation for teaching: book chapters; articles from periodicals or newspapers; short stories, essays or poems; and charts, graphs, diagrams, drawings, cartoons or pictures from books, periodicals, or newspapers in accordance with these guidelines.

  This test probably does not apply to Web pages which are freely available to millions of users via any Internet Web browser.

• C. THE AMOUNT AND SUBSTANTIALITY OF THE PORTION USED.
  In most circumstances, copying the whole of a work cannot be considered fair use; copying a small portion may be if these guidelines are followed.

  Most third-party pages represented here have been excerpted only in part, and have not been copied in their entirety.

• D. THE EFFECT OF THE USE UPON THE POTENTIAL MARKET FOR OR VALUE OF THE COPYRIGHTED WORK.
  If resulting economic loss to the copyright holder can be shown, even making a single copy of certain materials may be an infringement, and making multiple copies presents the danger of greater penalties.

  This test is met since there is no economic loss from the use of the selected Web pages found in these archives.
