In the United States, “ad interim copyright”was a special short-term copyright
that applied to certain books and periodicals in the English language that were first manufactured and published outside the United States.

It was a partial exception to the manufacturing requirements of the previous U. S. copyright law. Its purpose was to secure temporary U. S. protection for a work, pending the manufacture of an edition in the United States.

The ad interim requirements changed several times over the years and were subject to a number of exceptions and qualifications.

The manufacturing provisions of the copyright act expired on July 1, 1986, and are no longer a part of the U.S. copyright law.

The transitional and supplementary provisions of the act provide that for any work in which ad interim copyright was subsisting or capable of being secured on December 31, 1977,
copyright protection would be extended for a term compatible with the other works in which copyright was subsisting on the effective date of the new act.

Consequently, if the work was first published on or after July 1, 1977, and was eligible
for ad interim copyright protection, the provisions of the present copyright act will be applicable to the protection of these works.

Anyone investigating the copyright status of an English-language book or periodical first published outside the United States before July 1, 1977, should check carefully
to determine:

• whether the manufacturing requirements were applicableto the work, and
• if so, whether the ad interim requirements were met.
