Typology of feminism

So, in undergraduate textbooks and so on, you tend to see feminism taught as being one of "three types": liberal feminism, socialist feminism, radical feminism. Does anyone have any idea where this typology came from? Rough date, origin(ator), etc.?

Alternate histories

Quite a few of them rattling around the Altariel headspace at the moment.

The Plot Against America by Philip Roth. Posits the defeat of FDR in the 1940 presidential race, and the election of pro-Nazi, anti-Semitic former air-ace Charles Lindbergh. Roth puts his own family into this situation: a Jewish family living in Newark (Philip starts the book as a seven-year old boy). ( Spoilers follow )

Death of a President: drama-documentary with a near-future setting, following what happens after George W. Bush is assassinated after giving a speech in Chicago in 2007. I had been expecting something pretty sensationalist, and in fact it was very low-key, very measured, very well made. It didn't make the world's subtlest point, but it was a good point, and worth making.

The Amazing Mrs Pritchard: Well, I suspect this is probably going to turn out to be pish, and you know it's all a mighty long way from A Very British Coup, but - god help me - I quite enjoyed episode 1. Because I'm not going to see Tony Blair concede an election any other way, am I? Mrs Pritchard herself is a vile busybody, and her husband is tediously opposed to her political career (I just think it would have been more fun for him to be a more bewildered version of Denis Thatcher than an excuse for CONFLICT). And there's some weird gender stuff going on (i.e. what democracy needs is an infusion of Women's Innate Good Sense!). But I'll watch on, out of sheer fascination, and because I think it's quite positive to put something on prime time going, "Politics is really, really important, and you can do something about it!"

Children of Men: Bloody bloody bloody hell, that was outstanding.
