+ 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.

In the case of works reproduced in three-dimensional copies, identifying material such as photographs or drawings is ordinarily required.  Other examples of special deposit requirements (but by no means an exhaustive list) include many works of the visual arts such as greeting cards, toys, fabrics, oversized materials (request “Deposit Requirements for Registration of Claims to Copyright in Visual Arts Material” [http://www.loc.gov/copyright/circs/circ40a.pdf]); video games and other machine-readable audiovisual works (request Circular 61 [http://www.loc.gov/copyright/circs/circ61.pdf]); automated databases (request Circular 65 [http://www.loc.gov/copyright/circs/circ65.pdf] , “Copyright Registration for Automated Databases"); and contributions to collective works.  For information about deposit requirements for group registration of serials, request Circular 62 “Copyright Registration for Serials.” [http://www.loc.gov/copyright/circs/circ62.pdf] ,

If you are unsure of the deposit requirement for your work, write or call the Copyright Office and describe the work you wish to register.

Unpublished Collections

Under the following conditions, a work may be registered in unpublished form as a “collection,” with one application form and one fee: 

  + The elements of the collection are assembled in an orderly form;

  + The combined elements bear a single title identifying the collection
    as a whole;

  + The copyright claimant in all the elements and in the collection as
    a whole is the same; and

  + All the elements are by the same author, or, if they are by
    different authors, at least one of the authors has contributed
    copyrightable authorship to each element.  An unpublished collection
    is not indexed under the individual titles of the contents but under
    the title of the collection.

NOTE:  A Library of Congress Catalog Card Number is different from a copyright registration number.  The Cataloging in Publication (CIP) Division of the Library of Congress is responsible for assigning LC Catalog Card Numbers and is operationally separate from the Copyright Office.  A book may be registered in or deposited with the Copyright Office but not necessarily cataloged and added to the Library’s collections.  For information about obtaining an LC Catalog Card Number, see the following homepage:  [http://lcweb2.loc.gov/pcn].  For information on International Standard Book Numbering
