This reference volume compiles official copyright renewal registrations issued by the United States Copyright Office during the second half of nineteen sixty-four. It serves as an authoritative historical record for bibliographic researchers, legal scholars, and publishers seeking to verify the copyright status of works originally published decades earlier.
The text is structured as a comprehensive directory. Entries are primarily arranged in alphabetical order by the name of the author, corporate body, or issuing organization. For serial publications and specific collective works, entries are organized by title to facilitate efficient cross-referencing.
Each entry provides dual registration details. Readers find specific information relating to both the original copyright registration and the subsequent renewal registration, including exact dates, original registration numbers, and the names of renewal claimants.
The volume meticulously documents works contributed to periodicals, pamphlets, and full-length books. It also incorporates cross-references from variant names, joint authors, editors, and renewal claimants to ensure complete traceability across complex publishing histories.
By systematically recording these renewals, the publication preserves the legal continuity of thousands of literary works. It acts as an indispensable tool for determining whether specific mid-century publications remained under copyright protection or entered the public domain.
The catalog maintains a strictly administrative and objective tone throughout its pages. Its exhaustive compilation reflects the rigorous legal recording practices of the Library of Congress during a period of significant literary output.
