There’s one more thing you should be aware of when using public domain works: copyright restoration. Restoration? But don’t public domain works always stay in the public domain? Well, in the case of certain works that were first published outside the US ... no.
Here’s the deal. Works from certain countries that were in the public domain because they didn’t comply with formalities of US law (like notice and renewal requirements), or because they were published in countries that didn’t have copyright relations with the US (like the Soviet Union before 1973) had their copyrights restored on January 1, 1996. This happened through the Uruguay Round Agreements Act (URAA), which implemented the General Agreement on Tariffs and Trade (GATT). (If you care about such things, the URAA is Pub. L. No. 103-465, 108 Stat. 4809, enacted December 8, 1994.)
To be eligible for copyright restoration, a work must meet all of these requirements:
Note: Works that are in the public domain for reasons other than failure to comply with copyright formalities, or lack of US copyright relations (works whose full US copyright term has expired, for example), are not eligible for copyright restoration.
Works that meet the restoration requirements have a copyright term equal to what they would have had they complied with all US formalities. The US copyright term for works published before January 1, 1978, generally lasts for 95 years from the year of first publication. For works published on or after January 1, 1978, copyright lasts for the life of the author plus 70 years. For example:
Here’s a small sample of works that have had their US copyrights restored:
... and there are countless others. But you get the picture, I’m sure. It’s very unlikely that a work first published abroad within the last 50 years will be in the US public domain. Just so you know.
Caveat: The URAA copyright restoration rule (which amended US copyright law as 17 USC § 104A) generally will apply to works of this ilk ... but there’s a different rule in the US Ninth Circuit. In the Ninth Circuit works that were first published outside the US without a valid copyright notice will be treated the same as unpublished works.
Because copyright restoration is automatic, there is no list of restored works that you can consult. No documents needed to be filed. If the work was eligible, end of story. As of January 1, 1996, the work was removed from the US public domain and the copyright owner can sue others for infringement. But ...
Using a restored work without permission after January 1, 1996, is copyright infringement. But what about people who began using these works before the URAA was enacted (December 8, 1994), relying on the fact that they were public domain works?
Such people are called (in legal speak) reliance parties (makes sense, yes?). Since their use was perfectly legal (these works actually were in the public domain, remember), the URAA requires owners of restored copyrights to notify reliance parties if they plan to enforce their rights.
The owner of a restored copyright can’t enforce his or her rights against reliance parties unless he or she notifies them:
If the owner chose to go the constructive notice route (filing the NIE with the Copyright Office) and the source country was a member of the Berne Convention or the WTO as of January 1, 1996, that owner must have filed the NIE between January 1, 1996, and December 31, 1997. So ... the filing window has closed for most countries of the world.
The law requires the Copyright Office to publish lists identifying restored works where NIEs have been filed. (The lists are published in the Federal Register). These lists can be helpful if you’re unsure about the public domain status of a work that was first published outside the US. Just remember, though, that copyright restoration is automatic for eligible works and NIEs are only used to notify reliance parties of the owner’s intent to enforce the copyright.
The Copyright Office states here that you can search records of NIEs through the Copyright Catalog of Documents (but the link is dead, at least as of 5/6/2013). You can also view the titles of restored works that have been published in the Federal Register here as well.
Many works that were first published outside the US have had their copyrights automatically restored. (Nobody knows how many, but it’s got to be a big-ass number.) Remember, though ... not all works are eligible for copyright restoration. Still in the public domain in the US are:
Yep, this really is the end of the tutorial. Finally. I hope it’s been helpful. If it has, I’d love it if you’d let me know. And if you have any questions, ditto.
