I would like to include previously copyrighted material in my dissertation. Do I need permission?
 
Including material produced by other authors in your dissertation or thesis can serve a legitimate research purpose, but you want to be careful to avoid copyright infringement in the process. Copyright law protects original works of authorship, and republishing someone else's work, even in abbreviated form, requires permission from the author or copyright owner. If you intend to include material covered under another copyright, you must receive permission from the author(s) and include it with your submission before we can publish it in your dissertation or thesis.

For more detailed guidance on avoiding copyright infringement, please see our Copyright Guide. In addition, Dr. Kenneth D. Crews, a Professor at Indiana University's School of Law, has kindly given us permission to provide free access to his booklet Copyright Law and Graduate Research: New Media, New Rights, and Your New Dissertation. It provides a detailed overview of copyright law that no new dissertation author should miss.
