COPYRIGHT REGISTRATION
In general, copyright registration is a legal formality intended to make a public record of the basic facts of a particular copyright. However, registration is not a condition of copyright protection. Even though registration is not a requirement for protection, the copyright law provides several inducements or advantages to encourage copyright owners to make registration. Among these advantages are the following:
Registration establishes a public record of the copyright claim.
Before an infringement suit may be filed in court, registration is necessary for works of U. S. origin.
If made before or within 5 years of publication, registration will establish prima facie evidence in court of the validity of the copyright and of the facts stated in the certificate.
If registration is made within 3 months after publication of the work or prior to an infringement of the work, statutory damages and attorney's fees will be available to the copyright owner in court actions. Otherwise, only an award of actual damages and profits is available to the copyright owner.

A nonreturnable deposit of the work being registered. The deposit requirements vary in particular situations. The general requirements follow. Also note the information under "Special Deposit Requirements."
If the work was first published in the United States on or after January 1, 1978, two complete copies or phonorecords of the best edition.
If the work was first published in the United States before January 1, 1978, two complete copies or phonorecords of the work as first published.
If the work is an unpublished or published computer program, the deposit requirement is one visually perceptible copy in source code of the first 25 and last 25 pages of the program. For a program of fewer than 50 pages, the deposit is a copy of the entire program. For more information on computer program registration, including deposits for revised programs and provisions for trade secrets, request Circular 61, "Copyright Registration for Computer Programs."
If the work is in a CD-ROM format, the deposit requirement is one complete copy of the material, that is, the CD-ROM, the operating software, and any manual(s) accompanying it. If registration is sought for the computer program on the CD-ROM, the deposit should also include a printout of the first 25 and last 25 pages of source code for the program.
