Bibliophilia

I had a whole week off ordering books. Now I've proved I can quit anytime, I no longer feel the need to. So I've just ordered A. S. Byatt's The Children's Book and Richard Overy's The Morbid Age: Britain Between the Wars. I was also sorely tempted by Ernest Millington's memoir (he died yesterday, the last Common Wealth Party MP) but resisted.

I can quit any time

Got to switch off now - just ordered a biography of Tom Wintringham, a hero of the British left. He's interesting on his own, but I'm really looking for histories of the Common Wealth Party, a 1940s liberal Socialist party which had 5 MPs at one point, including Wintringham. Any know of any?
