"Catalog of Copyright Entries: Third Series, Volume 27, Parts 12–13, Number 1" is a scientific publication written in the early 1970s. This catalog serves as a formal record of motion picture copyright registrations in the United States during the first half of 1973. It systematically enumerates and describes a wide array of motion pictures, including feature films, industrial films, and educational content, thus providing an extensive reference for copyright claims in this domain. At the start of the catalog, the introduction outlines its purpose alongside details about its organization. The catalog is divided into two main sections—current registrations and renewal registrations, arranged by title. Each entry encompasses various details such as the title, production statement, running time, and copyright claim information, offering a comprehensive look at motion pictures registered during the specified timeframe. The preliminary pages also explain ordering information and the relevant sections of U.S. copyright law, underscoring the catalog's role in legal and archival contexts.

The United States Copyright Office (USCO), a part of the Library of Congress, is a United States government body that registers copyright claims, records information about copyright ownership, provides information to the public, and assists Congress and other parts of the government on a wide range of copyright issues. It maintains online records of copyright registration and recorded documents within the copyright catalog, which is used by copyright title researchers who are attempting to clear a chain of title for copyrighted works.
