Copyright Term and the Public Domain in the United StatesA chart created by Cornell University Library Copyright Information Center 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.
Can I Use It Without Asking?
✅ 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.
Where to Find Public Domain Content
💡 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.
