hth Act extended it to
December 31, 1974; the ninth Act extended it to December 31, 1976, and
the Copyright Act of 1976 finally extended the copyright through the
end of 1982 (75 years from the end of the year in which the copyright
was originally secured).

==================================================================
COPYRIGHTS SECURED BETWEEN JANUARY 1, 1950, AND DECEMBER 31, 1963:
RENEWAL WAS NECESSARY
==================================================================

Copyrights whose first 28-year term of copyright was secured between
January 1, 1950, and December 31, 1963, including works protected in
their first term under the Universal Copyright Convention, still had to
be renewed within strict time limits in order to receive the maximum
statutory duration. U.S. adherence to the Berne Convention did not alter
this requirement. Renewal registration had to be made within a year
period beginning on December 31 of the

--3--

27th year of the copyright and running through December 31 of the
following year.

If a valid renewal registration was made at the proper time, the second
term lasts for 67 years. This is 39 years longer than the 28-year renewal
term provided under the 1909 law and makes the two terms of protection
for the renewed copyright last for a total of 95 years. However, if
renewal registration was not made within the statutory time limits, these
copyrights expired at the end of their first terms and protection was
lost permanently.

=================================================================
COPYRIGHTS SECURED BETWEEN JANUARY 1, 1964, AND DECEMBER 31, 1977
=================================================================

The amendment to the copyright law enacted June 26, 1992, makes renewal
registration optional, and the amendment enacted October 27, 1998,
further extends the renewal term to 67 years. The copyright is still
divided between a 28-year original term and a 67-year renewal term, but
the renewal term automatically vests on December 31st of the 28th year. A
renewal registration is not required to secure the renewal copyright.
Certain benefits accrue to making renewal registrations, and the
Copyright Office continues to accept renewal applications. See Circular
15, "Renewal of Copyright," for a discussion of the benefits of making
renewal registration.
