I am aware that PhD theses can be self archived in university site, personal webpage or sites like researchgate (ePrint Archive for PhD Dissertation in the Social Sciences).
I am not really fond of researchgate. I wish to know if arXiv (or biorXiv; as my field is biology that involves both mathematical modelling and experimental techniques) allows archiving of PhD thesis. This is not explicitly mentioned in these sites but this university site provides instructions on submitting PhD thesis to arXiv. I think this would be better than self archiving because arXiv submissions receive a DOI (I guess).
Does anyone have an experience with this? Are there other public repositories like arXiv that allow submission of PhD/masters theses (especially those that are biology related or accept all disciplines of science)?
