Colin Dobinson. Building Radar: Forging Britain's Early Warning Chain, 1935-1945. London: Methuen, 2010. Looks like a useful complement to David Zimmerman's Britain's Shield (2001). This covers the scientific and institutional side of the British development of radar in detail too (and adds some texture to the role of death ray desire), but is more concerned than is Zimmerman with the operational and technical side of the programme, as well as with the physical survival of radar sites (since the book is part of an English Heritage series).
Stuart Hylton. Reporting the Blitz: News from the Home Front Communities. Stroud: History Press, 2012. A thematic exploration of the non-London Blitz as seen through the provincial press: the black-out, evacuation, anti-gas drills, entertainment, war aims, and even air raids. Some chapters stray outside the Blitz, for example one on attitudes towards Britain's allies (mostly meaning the Soviet Union and the United States, though at least Canada gets a mention). Well-illustrated with relevant newspaper advertisements.
