The copyright for content on the website and the mordell.ca domain, for the most part, belongs to yours truly (i.e. Devon Mordell) or, in cases of collaborative projects, to my partners as well. For any other works on the website I have used, I was reasonably certain that they were in the public domain (and no, working in a copyright office for a year doesn't make me an expert - you'll have to make your own determination based on the acknowledgements page if there's anything you'd like to repurpose).
You can make a copy for your own personal or research use, or for other non-commercial purposes provided that you attribute the creator (with a link to where you found it if possible).
If your use doesn't fall under any of the cases listed above, you can always ask permission by contacting me at dmordell [at] uwindsor.ca.
