Congress," or simply, "Copyright, 1906,
by A. B." The omission of such a notice from the book would make it
impossible for its owner to prevent its being reprinted. There is a
penalty of $100 for using the notice of copyright in an uncopyrighted
book, and when the notice is used, there is a penalty of $25, if the
two copies as required by law are not deposited. This latter penalty
also applies in the case of failure to deposit one copy of a new
edition differing from the former one, if a notice of copyright is
used in the new edition.

In order to obtain a renewal of a copyright, the claim and the title
must be filed on a form provided for the purpose with the Register of
Copyrights "within six months before the expiration of the first
term," which would be sometime between twenty-seven and one-half and
twenty-eight years from the date of filing the original title. The
copyright period runs from the date of filing the original claim, and
not from the time of depositing the books, and great care should be
taken to ascertain the date of the registration of the original title,
and to compute the time so that the filing of the application for
renewal will surely fall within the specified six months. The renewal
period is fourteen years, and the fees are the same as in the case of
the original application, but a certificate, or copy of the record, of
the renewal claim must be taken and paid for by the claimant.

Only one copy of a book is required to be deposited to complete the
claim for a renewal term of copyright. This copy also must be
delivered within "six months before the expiration of the first term,"
and should be accompanied by a receipt as in the case of the original
deposit. In order to complete the claim, a copy of the certificate
must be published verbatim, within two months of the date of renewal
for four weeks in one or more newspapers printed in the United States.

In obtaining international copyright, publication on the same day here
and abroad is necessary, and this is sometimes a cause of considerable
inconvenience in actual practice. When a New York publisher wishes to
copyright in England a novel which he is about to publish, he must
prepare six special copies of the finished book, bind them in cloth,
print the copyright notice on the back of the title-page, and the name
and address of the London firm or the individual who is willing to act
as the English publisher of the book, and forward the copies
