To establish a copyright you must simply print the below notice,
either on the cover or the page immediate following the cover in
your book, report, etc.

There it is:

© 2006, John Doe, or Copyright 2006, John Doe.

Most people do not know that you are in fact NOT required to register
the copyright with the copyright office***, but if you DO wish to
register it, write to them for the necessary application form.

You then submit two copies of the publications along with the
application form for each copyright.

For necessary forms and
additional information, write:

Register of Copyrights, Library
of Congress, Washington DC 2055
