When a book is deposited for registration, accompanied by the claim for
copyright, preferably on the application form gratuitously provided by
the Copyright Office, its class designation, with its accession or
sequence number in that class, is at once stamped upon the deposit copy
or copies, with the date of receipt, and also upon a green record slip
on which all details in the progress of the work through the Copyright
Office are recorded with exact time of each act and the initials of the
respective clerks. This record, when completed, shows, besides the class
number and the title of the work, the date and hour of the receipt of
deposit copies and of the receipt of application, affidavit and fee,
with memorandum of the disposition of the fee if out of the ordinary
course; the examination of the application and affidavit, the
preparation of the white card for printer's copy, and the clearance of
the work. Thus cleared, the book is ready for examination by the Library
Commission, the delivery of one copy to the Catalogue Division of the
Library of Congress, the making of the certificate and its record and
the making of the index cards, all of which acts are performed usually
on the day of receipt, or otherwise as early as practicable on the
following day. The record slip also provides for noting and notifying
claimants of defects as to the deposit copies or the application for
copyright, and for noting also the reference to other departments, and
the disposition of second deposit copies.
