How can I find the copyright owner?
<p>The American composer Leo Sowerby died on July 7, 1968.  At first there were three ways of contacting his heirs:  1. via the Sowerby Foundation, run by his friend Francis Crociata.  They had a newsletter, a website, etc.  But Mr. Crociata has since passed away, the website has disappeared, and anything sent to their old address bounces back.  2. His executor was Ronald Stalford who though not a relative himself, knew hot to contact the heirs.  Mr. Stalford has since passed away and I have been unable to find out who took his place as executor.  3. The Washington National Cathedral, where Dr. Sowerby worked for the last several years of his life, used to know how to contact the heirs, but has lost touch with them.</p>

<p>I want to copy a handwritten manuscript on file at the Library of Congress.  Without permission from the copyright owner, they'll let me look at it, but that's it, and I need a copy for some research I'm doing.</p>

<p>Are there any provisions for copying if, following reasonable diligence, the copyright owner can't be found?</p>

<p>There is a good chance that the letter in question is in the public domain. Prior to 1978, the copyright laws were very different. Also, if it was published in 1963 or earlier and there was an initial claim of copyright but the copyright was not renewed, it would also be in the public domain.</p>

<p>A convenient table summarizing when various pertinent categories of works enter the public domain can be found <a href="http://copyright.cornell.edu/resources/publicdomain.cfm" rel="nofollow noreferrer">here</a>. </p>

<p>It might be possible to construe depositing the work with the Library of Congress as either a "publication" of the work (which if it happened before 1964 would put it in the public domain), or as a relinquishment of the copyright to the public domain, although I am not a specialist familiar with the legal effect of different forms of donations to the Library of Congress and it could depend upon the facts and circumstances of that particular donation to the Library of Congress.</p>

<p>If worse came to worse, I imagine it might be possible to seek a declaratory judgment that your use was a fair use with substituted service on the heirs, and seek a default judgment, although that would not be optimal.</p>

<p>The general problem that you face is that the work in question is what is called an "<a href="https://en.wikipedia.org/wiki/Orphan_works_in_the_United_States" rel="nofollow noreferrer">orphan work</a>". Many other countries have special procedures to allow the use of orphan works, but the U.S. has resisted such legislation except for a narrow exception applicable only to libraries and archives at <a href="https://www.law.cornell.edu/uscode/text/17/108" rel="nofollow noreferrer">17 U.S.C. § 108</a>.</p>
