This link was made after a language model re-read the damaged OCR (deepseek-ai/DeepSeek-V4-Pro); the reading was accepted only because the number and date or title it reported agree with the catalog. Its note: “Original date '3Apri6' interpreted as 3Apr46 (1946-04-03) based on renewal year 1973. Original number M2728 likely MP2728 (motion picture). Renewal date '7May733' corrected to 7May73 (1973-05-07).”
