I have published a research paper based on my masters thesis. The name of the research paper is same as that of my thesis. The copyright to the paper is held by the journal in question. Now I want to publish my thesis in ProQuest. Will I run into trouble for the same name?
Your copyright should not be an issue, provided that you either are the sole owner of the copyright, or that you have provable permission of the owner/contributors to use the same name.
But on that note, names aren't easily copyrighted. There are thousands of papers, books, magazine articles, and other such that include the same kind of name as each other, and I would bet that there are one or two sharing your paper's exact name.
If anything or anyone happens to do research of their own and says anything about it, which I personally doubt will happen, but hey... Just prove that you are the owner of the document, or allowed by other contributors to use it.
