Catalog of Copyright Entries. Third Series: 1958: January-June

The Catalog of Copyright Entries serves as an essential administrative record produced by the United States Copyright Office within the Library of Congress. This specific volume, covering the period from January through June of 1958, represents the transition toward more rigorous documentation of intellectual property in the mid-twentieth century. Its primary purpose was to provide a public, searchable archive of registered works, including books, pamphlets, periodicals, and contributions to newspapers, ensuring that creators and the public had a centralized reference point for legal claims.

The design of these catalogs followed strict bureaucratic standards for data organization, emphasizing legibility and consistency over aesthetic flair. Compiled by Library of Congress staff, these volumes were intended for use by librarians, legal professionals, and publishers rather than the general public. While they were not designed as trade literature, their reception among researchers has been significant, as they remain one of the most reliable primary sources for determining the publication status and ownership history of works copyrighted during the post-war era.
