Motion pictures are often based on other works such as books or
serialized contributions to periodicals or other composite works. *If
you desire a search for an underlying work or for music from a motion
picture, you must specifically request such a search. You must also
identify the underlying works and music and furnish the specific titles,
authors, and approximate dates of these works.*

Searches Involving Assignments and Other Documents Affecting Copyright
Ownership

For the standard hourly search fee, the Copyright Office staff will
search its indexes covering the records of assignments and other recorded
documents concerning ownership of copyrights. The reports of searches in
these cases will state the facts shown in the Office's indexes of the
recorded documents but will offer no interpretation of the content of the
documents or their legal effect.

LIMITATIONS ON SEARCHES
-----------------------

In determining whether or not to have a search made, you should keep the
following points in mind:

NO SPECIAL LISTS. The Copyright Office does not maintain any listings of
works by subject or any lists of works that are in the public domain.

CONTRIBUTIONS NOT LISTED SEPARATELY IN COPYRIGHT OFFICE RECORDS.
Individual works such as stories, poems, articles, or musical
compositions that were published as contributions to a copyrighted
periodical or collection are usually not listed separately by title in
our records.

NO COMPARISONS. The Copyright Office does not search or compare copies of
works to determine questions of possible infringement or to determine how
much two or more versions of a work have in common.

TITLES AND NAMES NOT COPYRIGHTABLE. Copyright does not protect names and
titles, and our records list many different works identified by the same
or similar titles. Some brand names, trade names, slogans, and phrases
may be entitled to protection under the general rules of law relating
