Motion pictures, January-June 1977 : $b Catalog of copyright entries, third series, volume 31, parts 12-13, number 1

The catalog provides a systematic record of every motion‑picture copyright registered in the United States during the first half of 1977. Each entry lists the claimant’s name, registration date, and number, along with a concise description of the work, whether it is a photoplay, a documentary, or another type of film. The classification codes (L for photoplays, M for other motion pictures) help users quickly sort the material for research or legal purposes.

Designed for librarians, filmmakers, and scholars, the volume also explains the statutory framework that governs copyright registration, offering insight into the procedural rules that were in effect at the time. The introductory notes describe how copies of the works were deposited and how the data can serve as prima facie evidence in court, underscoring the catalog’s official standing.

Beyond the listings, the publication details the pricing structure for individual issues and subscriptions, and it invites feedback from users to improve future editions. Its clear layout and thorough indexing make it a practical tool for anyone needing authoritative reference to mid‑1970s American motion‑picture copyrights.
