Unless otherwise noted, documents posted in Trace are the property of their respective authors. Authors who deposit material in the repository agree to the following:

I hold the copyright to this document, or have been authorized by the copyright holder(s) to upload it for distribution, and agree to permit this document to be posted in Trace, and made available to the public in any format in perpetuity.

To the best of my knowledge, I warrant that the posting of the work does not infringe any copyright, nor violate any proprietary rights, nor contains any libelous matter, nor invade the privacy of any person or third party, nor otherwise violate Trace policies.

All permission requests should be directed to the individual authors or the stated holders of copyright. The University of Tennessee claims no rights over the content in Trace. For more information about copyright, please see the University Libraries Scholarly Communication Copyright pages at //www.lib.utk.edu/scholar/copyright/. Go to SHERPA/RoMEO to search for your publisher's copyright policy. Authors must own the copyright for work submitted to Trace. Authors grant the university a non-exclusive, perpetual right to use the digital assets for non-commercial use. Because authors retain the copyright for all content posted in the repository, they are free to reuse the content elsewhere.

If a working paper is published in a journal - either in the same form or, more commonly, in revised form - many journals allow the working paper to continue to be openly accessible, especially when it is for educational/scholarly noncommercial use. While some journals require that the working paper be removed, others grant exceptions for institutional repositories, but must be asked.

The author is responsible for negotiating the terms of publication agreements. The repository constitutes noncommercial use. Faculty who wish to include a reprint of a journal article in the repository should consult their agreement with the journal to see if posting in a repository is allowed. Authors who have transferred copyrights may seek permission of the copyright holder to publish it in the repository. The SHERPA/RoMEO site provides information about publisher copyright policies.
