Motion pictures, 1977 : $b Catalog of copyright entries, third series, volume 31, parts 12-13

"Motion pictures, January-June 1977" by Library of Congress Copyright Office is a government bibliographic catalog written in the late 20th century. It compiles the semiannual motion-picture portion of the Catalog of Copyright Entries, documenting U.S. registrations and renewals for photoplays and other films, with detailed indexing and reference notes. The volume’s focus is practical and archival, serving librarians, lawyers, and film researchers who need authoritative registration data. The opening of this catalog establishes its official status and use in evidence under U.S. copyright law, provides ordering and subscription details, and explains the scope: parts 12–13 covering classes L (photoplays) and M (other motion pictures). It outlines filing rules for the index, lists the data fields included in each main entry (from titles and authorship through claimant, publication date, and registration number), explains how discrepancies and renewals are noted, and mentions Library of Congress selection and printed cards. A price list for all series parts, a tally of registrations for the period, and an extensive “Abbreviations and Symbols” key prepare readers to interpret entries. The section then begins the alphabetical Index, giving names and titles paired with their registration numbers before the detailed records to follow. (This is an automatically generated summary.)
