I want to cite a MOOC, but the MOOC is no longer running. The URL I saved only takes me to the course homepage, not the page giving the information I used. Is this acceptable for a reference? This is the page I end up on, but my citation is linked to peer to peer learning within the MOOC.
Actually, the problem is deeper than this. The web is volatile. Any time you cite the web with a url, give the date that you accessed it.
So, if you have a date, even just a month, say, then give the url and the date.
There are resources like the Wayback Machine that archive web sites. It might be possible that the pages you need can be found there.
