Adding to Glen's  excellent post on the subject, a
person can make it clear to the reader or  user of the
work that the work is an original work and is
copyrighted by  him, by stating so and using the
copyright symbol on web sites, printed  material and
other media stated in the Act.

This does not constitute  registration of the copyright
under the law, but it does show claim to  ownership of
the work and is useful as evidence for filing suit  for
copyright infringement in court.  As Glen said,
registration of  copyrighted material is not required
for protection under the  law.

In the case of schematic diagrams, I've heard that a copyright applies only  
to the artwork itself. So, the original diagram cannot be copied, but it's  OK 
to re-draw it, then it's legal to copy. If the circuit is to be  protected, 
the design must be patented, not just a copyright on the  circuit drawing. 
Anybody know if that is definitely true?
