How do I verify that content is public domain?
Verify public-domain status before republishing or selling an old work. The publication date is a clue, not proof by itself.

Public-domain status must be verified for the specific work and jurisdiction; age alone is not enough to justify reuse.
A practical way to think about it
- Identify the exact work, edition and source you plan to use.
- Verify its copyright/public-domain status using reliable records or guidance.
- Check whether later editions, translations, images or added material have separate rights.
- Keep a record of the source and your verification.
Watch for layers of rights
An original text may be public domain while a modern translation, introduction, photograph, illustration or edited edition is still protected. Verify the actual material you intend to reuse, not merely the title of the underlying work.
A simple beginner example
If you find an old book online, record the author, publication date and edition, then verify the status of that edition and any added images or editorial material before building a product from it.
