Rights & Public Domain
Four foundational guides. Each explains the core rule in plain language, identifies important exceptions, and links directly to the original legal or official sources.
Do I automatically own copyright in what I write?
Creation, fixation, ownership, registration and the difference between protecting a work and protecting an idea.
Read the guide →Can I republish a poem after a journal prints it?
What to check in your agreement, including exclusivity, scope, duration and permissions for collected editions.
Read the guide →What counts as fair use?
The four statutory factors, why there is no magic word count, and how to approach quotations and reproduced images.

Check the source, not just the answer.
Each entry distinguishes an established rule from a question that depends on contracts, publication history or jurisdiction. We link to statutes and U.S. Copyright Office materials wherever possible.
These guides are general educational information, not individualized legal advice. A public-domain determination for a specific edition, translation, artwork or recording may need further research.
We mark when an entry was last checked and correct errors transparently. Reader-submitted corrections will be enabled when the independent AI correction intake is deployed. No automated legal-status verdicts without document-level verification.
