Book Production Disparity (Quality Publishers?)

[Resurgam13]

I recently read a short monograph on "Publishing in Wartime" with regard to the Second World War but one paragraph I found of particular interest was when the so-called "authorized economy standard" was being imposed on Publishers about 1941. The last hold-out was Jonathan Cape, "who maintained higher standards than most" and it struck me, as a collector, that most Cape volumes pre-1939 are usually found in much better condition than some other Publishers I could name, particularly Hutchinson and Hodder & Stoughton. Pre-war Macmillan volumes also seem, in general, to have weathered better than others (which the exception of the fading to the covers of the Official Histories), as do Faber and Gollancz. Herbert Jenkins seemed invariably, to use poorer quality paper, with Constable and Cassell being slightly better than, though not up to the standard of, Cape.

I wonder if anyone else has views on the various Publishers of First World War volumes?

Kind regards,

Geoffrey
