It is generally the custom to obtain a copy of this record, which, if the fee is enclosed, is sent to the claimant as soon after the receipt of the application as it can be made out in the regular course of the business of the Copyright Office. This copy is signed by the Register of Copyrights and is sealed with the official seal of the Library of Congress. The period of protection under an original claim is twenty-eight years.
It is important to remember that the application and the title are required by law to be delivered to the Register of Copyrights "on or before the day of publication in this or any other country." If delayed until after that day, the book cannot have the protection of the copyright law.
Prior to 1891 none but citizens or residents of the United States could obtain copyright, but in July of that year the privilege was extended to the citizens, or subjects, of such other countries as grant to the citizens of the United States the same copyright privileges which they afford to their own countrymen. At the present time these privileged countries are Belgium, France, Great Britain and her possessions, Switzerland, Germany, Italy, Denmark, Portugal, Spain, Mexico, Chile, Costa Rica, the Netherlands (Holland) and her possessions, Cuba, China, and Norway.
The law also requires that a book desired to be copyrighted in the United States must be printed in this country. It is, therefore, not possible to copyright a book which has been put into type and electrotyped in England and sent here for the presswork and binding. Copies of a book manufactured in this country may, however, be sent to England and copyrighted there.
The second step is to send two copies of the printed book for deposit in the Copyright Office, and until this has been done, the copyright is incomplete. These copies, like the title, must be delivered on or before the day of publication.
A printed receipt-form for books to be deposited is supplied by the Copyright Office, and it is the usual practice for the sender to fill in his address, and the names of the book and of the author, so that when the books are received, the Register of Copyrights needs only to date and sign the receipt-form and return it to the sender. This receipt-form should be enclosed with the books when they are forwarded. The package must be plainly addressed (the Copyright Office furnishes printed labels if desired) and sent, carriage prepaid, through the mail.
