I'm interested in publishing parts of my PhD thesis in advance and I'm wondering wether or not this will result in problems later on. One of the problems I'm thinking of is that usually the copyright is transferred to the journal/publisher but at our university you are required to publish your thesis online via the library website, which means you have to give them the right to publicize the thesis (which I'm not sure you still can do, even when a slightly modified version of the journal paper is only part of the thesis).
So I guess my question is this:
Is it common practice to publish parts of a PhD thesis in advance and if so does this result in legal problems? What are your experiences?
