I find MLA (in its current incarnation) one of the more congenial for my kind of work. That business of "Tolkien 1983" is truly horrible for anyone trying to write on literature in its historical context.

One thing I've noticed in recent versions of the MLA is that they've dropped the requirement for including the URL for websites. I can see why, I suppose - URLs aren't all very stable - but I think it's a mistake. Simply referring to sites by their names ("The Tolkien Lover's Site" or whatever) isn't sufficiently precise, to my mind.
