During the night, I remembered that, somehow in these searches, I was led to an important Wikipedia page on 'Economic Antisemitism':
One of the infuriating things about using computers is that it is easy to hop around the internet and not remember how you got were you are.
In 'the old days' of physical libraries and things like Chemical Abtracts in print form, I seemed to be better organised in terms of *wring down in a book*! where I was going and what I'd found.
Now . . .
Anyway, that page on Economic Antisemitism looks to be worth a re-read . . .
