Contrary to incorrect information that has been put out here and elsewhere on the internet before, the Uruguay Round Agreements Act (URAA) restored or retroactively granted copyright to an entire set of works automatically. Whether or not a Notice of Intent to Enforce (NIE) was filed with the US Copyright Office does NOT affect whether or not the copyright is valid and enforceable (except against reliance parties). This page is a guide to determining whether or not a work is copyright-protected in the US due to the URAA.
Any work that meets all of the following requirements:
Any of the following would demonstrate that a work is not URAA-eligible:
Note: there is also a special exception for copyrights which were administered by the Alien Property Custodian (by citizens of enemy states of the US in World War II) and, if restored, would belong to a government or instrumentality thereof. This exception applies, for instance, to the World War II and earlier copyrights belonging to e.g., German citizens, but only if the copyright escheated to or was otherwise acquired by a government entity. This exception was written specifically to prevent Hitler from being granted a posthumous copyright in the United States and can be presumed to very rarely, if ever, apply to any work relevant to IMSLP.
Even if created by a foreign author, a work that was first published in the United States is subject to the same copyright notice and renewal requirements as other US works.
This does not affect the copyright status of the work. A reprint in the US does NOT indicate that the work is in the public domain. This applies even if the work is still being reprinted and sold in 1996 or later. See also the next section.
The URAA allows copyright holders for URAA-eligible works to file a Notice of Intent to Enforce (NIE) with the US Copyright Office for a period of two years following the restoration date. Lists of filed NIEs were published by the Copyright Office. Many popular and successful works which were URAA-eligible were included on these published lists.
There is a common misconception that the purpose of an NIE is to restore the copyright, or to make it enforceable in general, and that, if not filed, the work remains either in the public domain or with an unenforceable copyright. This is not correct.
The filing of an NIE is only relevant for a reliance party — that is, a person or organization that was actually using the copyrighted work before the restoration date. (Since this date is, in most cases, January 1, 1996, IMSLP and other online libraries can almost never be a reliance party.) A reliance party can continue to use the URAA-eligible work (under certain conditions), until/unless they receive an NIE. The purpose of a limited public filing period for NIEs was to create a public registry which reliance parties would have to check during the two-year period. Even after the public filing period ends, copyright holders can still send NIEs --- the only difference is that they now have to send them directly to reliance parties.
Yes, except against reliance parties (of which IMSLP cannot be one in virtually any case). These copyrights are fully enforceable, just as any other copyrights are.
A URAA-eligible work (a foreign work) could still be registered in the US. If the work was published originally or simultaneously in the United States, then it is not URAA-eligible, but a URAA-eligible work may well be registered. (If the publisher's address is a US address, this would be indicative that the original publication was in the US; if the address is foreign, then other evidence would be needed.)
A work published without a notice is still URAA-eligible (if the requirements are met).
Generally, this will be the country in which the work is first published.

For an unpublished work (as of the restoration date):
The Supreme Court specifically ruled this was constitutional in Golan v. Holder.
