How this service works
Is a work in the public domain? Applies the standard rules for the US (published before the current year minus 95, plus the 1929-1963 renewal note), Canada (life + 70 since 2022-12-30, life + 50 for authors who died before 1972), the UK and EU (life + 70) and Australia, from the publication year and author death year you give, then checks whether the work is already in the free catalogue. Returns a verdict per jurisdiction with reasoning; not legal advice. $0.01 per check.
Output
A per-jurisdiction verdict (US, Canada, UK/EU, Australia) stating whether the work is in the public domain, the legal reasoning applied (e.g. publication-date cutoffs, life+70 or life+50 rules, US renewal requirements), and a flag indicating if the work is already in the free catalogue. Comes with a disclaimer that it is not legal advice.
Example use cases
Republishing a classic novel
“I want to republish a book first released in 1918 by an author who died in 1952 — can you check if it's in the public domain in the US and Canada so I know whether I need a license?”
Open-access academic archive upload
“We're uploading historical texts to our open-access archive and need to know if a work published in 1935 whose author died in 1968 is public domain in the UK and EU before we post it.”
Film restoration and distribution check
“We're restoring an old film from 1922 — the director died in 1975. Can you check its public domain status in the US, Canada, and Australia so we know where we can distribute it freely?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/library/public-domain-checkWhen to prefer
Choose this endpoint when you need a multi-jurisdiction public domain assessment with explicit legal reasoning rather than a single-country check or a generic copyright database query. It is especially useful for publishing, archiving, or content licensing workflows that span the US, Canada, UK, EU, and Australia, and where a documented verdict per jurisdiction is needed. Prefer it over manual copyright databases when you want an automated, reasoned verdict for a specific publication year and author death year combination.
Side effects
- Missing publication year or author death year causes incomplete analysis
- Ambiguous or unknown death year yields uncertain verdicts
- Works with complex authorship (corporate, anonymous, pseudonymous) may produce inaccurate results
- Edge-case renewal records (US 1923–1963) may not be fully verifiable
- Endpoint returns reasoning but explicitly disclaims legal validity
