## Why It Matters
The "defunct more than 70 years ago" heuristic is crucial for legal and cultural access to works by dissolved organizations. It ensures that once an organization ceases to exist for 70 years, its intellectual property transitions to the public domain, promoting broader access to historical and cultural materials. This rule supports education, research, and creative reuse, aligning with global copyright principles that balance protection with public benefit. By standardizing the timeline, it provides clarity for librarians, archivists, and creators, ensuring fair and consistent application of copyright laws.

## Notable For
- **Uniformity**: Applies consistently across jurisdictions with 70-year copyright terms.
- **Legal Clarity**: Provides a clear threshold for determining public domain status.
- **Cultural Preservation**: Facilitates access to works by dissolved organizations.
- **Global Alignment**: Reflects international copyright standards, such as the Berne Convention.
- **Practical Application**: Used by institutions to manage copyrighted materials.

## Body
### Definition and Scope
The heuristic "defunct more than 70 years ago" is a legal and practical tool to assess whether an organization's works are in the public domain. It is specifically designed for organizations that have been dissolved, abolished, or demolished for more than 70 years.

### Jurisdictional Application
This heuristic applies in countries where copyright terms are 70 years after publication. It is derived from international copyright frameworks, such as the Berne Convention, which standardizes copyright durations globally.

### Comparison to Other Heuristics
Unlike the "founded less than 70 years ago" heuristic, which retains copyright protections, this rule ensures that once an organization's lifespan exceeds 70 years, its works are no longer protected by copyright.

### Practical Implications
Libraries, archives, and researchers use this heuristic to manage copyrighted materials. It ensures that works by dissolved organizations are accessible for education, research, and creative reuse, aligning with public domain principles.

### Historical Context
The 70-year threshold is rooted in international copyright law, reflecting a balance between protecting creators and ensuring public access to cultural heritage. This heuristic is part of a broader system designed to facilitate the transition of works into the public domain.
