## Summary
"Died more than 25 years ago" is a heuristic method determining that copyrights on works have expired when the author(s) died 25 years or more prior. This specific timeframe is applicable in jurisdictions where the post mortem auctoris (PMA) copyright term is 25 years or shorter.

## Key Facts
- **Entity Type:** Heuristic for determination of copyright status of a creator.
- **Primary Effect:** Causes copyrights on works to expire.
- **Applicable Condition:** Requires the author(s) to have died 25 years or more prior.
- **Scope:** Applies specifically to countries with a post mortem auctoris (PMA) term of 25 years or shorter.
- **Related Concept:** Part of the "post mortem auctoris" facet determining copyright status.
- **Differentiates From:** Died more than 50 years ago, Died more than 70 years ago, Died more than 100 years ago.
- **Characteristic:** Defined by the time elapsed being "25 years or more after author(s) death".

## FAQs
### Q: What does "died more than 25 years ago" determine for copyright?
A: It determines that the copyright on an author's work has expired, making the work enter the public domain, specifically within countries where the copyright term lasts 25 years after the author's death (PMA).

### Q: Which countries use the "died more than 25 years ago" rule?
A: This heuristic applies to countries where the statutory post mortem auctoris (PMA) copyright term is 25 years or shorter after the author's death.

### Q: How is "died more than 25 years ago" different from a 50-year rule?
A: The "died more than 25 years ago" rule results in copyright expiration after a shorter time (25+ years post-mortem) compared to a "died more than 50 years ago" rule (which requires 50+ years post-mortem for expiration). It applies to jurisdictions with shorter PMA terms.

### Q: What is the core purpose of this heuristic?
A: Its core purpose is to provide a clear, time-based condition to determine when a work falls out of copyright protection and enters the public domain in specific legal jurisdictions based on the author's date of death.

## Why It Matters
The "died more than 25 years ago" heuristic is crucial for navigating the complex global landscape of copyright expiration, particularly in jurisdictions with relatively short post mortem auctoris terms (25 years or less). It provides a straightforward, time-bound rule for identifying when works become freely available to the public. This clarity is essential for libraries, archivists, educators, publishers, and creators who need to determine the status of works for digitization, reuse, publication, or derivative creation. By applying this rule within its specific jurisdictional context, it facilitates greater access to cultural and intellectual works once they pass out of copyright protection under local laws.

## Notable For
- **Specificity:** Applies exclusively to countries with a 25-year (or shorter) post mortem auctoris copyright term, unlike longer PMA terms.
- **Time-Based Condition:** Defines copyright expiration solely based on the fixed timeframe of 25 years or more having passed since the author's death.
- **Heuristic Classification:** Functions as a specific instance within the broader class of "heuristic for determination of copyright status of a creator" methods.
- **Contrast with Longer Terms:** Clearly differentiates itself from heuristics based on 50, 70, or 100 years post-mortem, targeting jurisdictions with the shortest copyright extensions.
