Many universities enforce explicit policies regarding the delayed release (embargo) and/or restriction of dissemination of dissertations and theses. These policies may also apply to the delay or restricted shelving of a copy of your work in the university library. Such policies serve the scholarly convention of sharing one's research with others. Simply put, you are not contributing to your field or to general knowledge if others cannot examine the results of your scholarly work. When you instruct us to embargo or restrict dissemination of your dissertation or thesis, we assume that you are complying with the policies of your institution.University policies generally require that you petition for permission to embargo or restrict the dissemination of your dissertation or thesis. You will need to substantiate the reason for your request and receive approval from the required persons and/or authorities. Considerations that are likely to be deemed reasonable for granting permission to embargo and/or restrict dissemination include:


  • Patentable rights in the work or other issues in which disclosure may be detrimental to the rights or interests of the author.


  • The ethical need to prevent disclosure of sensitive or classified information about persons, institutions, technologies, etc.


  • The interest of an academic or commercial press in acquiring the rights to publish your dissertation or thesis as a book.


  • Content that is likely to be submitted to a peer-reviewed journal.

    The current embargo and restriction options offered by ProQuest are:


  • 6 month, 1-year, and 2-year embargoes
  • No search engine access
  • No sales via third party

    Embargoes start from the date we receive your manuscript at ProQuest. Note that there can be a delay of up to a semester at your institution before the work is forwarded to us.

    Additionally, please note that internet search engines are likely to find your dissertation or thesis through other access points, especially through the library or institutional repository at your graduate institution. If you truly need exclusion from search engines, you will need to petition for restriction at your graduate institution in addition to restricting such access through ProQuest/UMI.
