Copyright

A clear explanation of what the public domain is, with a definition and examples of materials that fall into it (e.g., works with expired copyright, government publications, and items dedicated by the creator).

Copyright does not last forever. When it ends, the work enters the public domain. But the rules vary depending on when and how the work was published.

The Cornell University Library Copyright Information Center created a chart to help determine the copyright status of a work and when it enters the public domain. It's a valuable resource for understanding copyright duration and how it applies to different types of works.

✅ Yes! Works in the public domain are free to use, copy, adapt, and share without seeking permission.

💡 Tip: Even when using public domain materials, it's good academic practice to give credit, especially in student work, publications, or instructional materials.

Note: Not all content that appears “old” is public domain. Always verify a work’s status if you're unsure.

💡 Tip: Many libraries and cultural institutions offer free access to public domain works. NWACC Library maintains a list of tools to help you locate usable materials for instruction, multimedia, or student projects.
