thank you for all these great links and for the review! I thought I should mention that, besides the
existing material, with the 100th anniversary of the breakup of WWI
the BBC is producing a lot of additional programmes (including daily reads of newsreels on the same days 100 years ago - these will keep going for the "duration of the war"), including a documentary by Katie Adie, a senior BBC war correspondent (one of her books was among those in issybird's list) - the trascripts are available here for all non UK residents:

A "Woman's hour" (BBC 4 radio programme) on what the war did for women is available as a podcast here (no geo restrictions):
