guide to investigating the copyright and renewal status of published work
is Samuel Demas and Jennie L. Brogdon, "Determining Copyright Status for
Preservation and Access: Defining Reasonable Effort," Library Resources and
Technical Services 41:4 (October, 1997): 323-334.

1961 Copyright Office study found that fewer than 15% of all registered
copyrights were renewed. For textual material (including books), the figure was
even lower: 7%.
4 These works may
still be copyrighted, but certification from the Copyright Office is a complete
defense to any action for infringement.
5
Presumption as to the author's death requires a certified
report from the Copyright Office that its records disclose nothing to indicate
that the author of the work is living or died less than seventy years
before.
