Doctoral candidates at the University of Chicago are required to grant ProQuest UMI Dissertation Publishing non-exclusive rights to reproduce and distribute their dissertations. If another publisher has accepted your manuscript for publication, you should be sure to retain the right to publish through ProQuest. Many scientific journals have standing agreements with ProQuest; most academic presses, however, do not.
Although doctoral candidates at the University of Chicago are required to grant ProQuest UMI Dissertation Publishing non-exclusive rights to reproduce and distribute their dissertations, authors hold the copyright for their own dissertations and retain the right to publish elsewhere. You may choose to register copyright or not, and you may register through ProQuest's ETD Administrator or through the United States Copyright Office.
Although it is not required, there are clear advantages to copyright registration. See Why copyright? for a list of advantages.
If your dissertation uses previously copyrighted material beyond fair use, you must obtain written permission from the copyright holder to include the material in your dissertation.
