604 1B

The film '604 1B' is a 1965 medical instructional film focusing on cytopathology (specifically the evaluation of cervical smears). Based on the US Copyright Office Catalog of Copyright Entries (CCE), Motion Pictures and Filmstrips (Volume 19, Part 12-13, Number 1), the film was registered for copyright by Cine-Graphic Projects, Inc. on March 1, 1965, under registration number MP15170. Under the Copyright Renewal Act of 1992, works first published or registered for copyright in the United States between January 1, 1964, and December 31, 1977, received an automatic renewal of their copyright for a second term of 67 years. Because this film was registered in 1965, it did not require a manual renewal filing to remain protected. Its copyright term will last for 95 years from the date of publication/registration, meaning it will not enter the public domain in the US until January 1, 2061.
