Alison,
If you're coming to the UK, check the COPAC catalogue. It has the holdings for just about every university in the UK. If you're going to be at a particular research institution for any period of time, you may be able to arrange for resources to be sent to you on inter-library loan.
Best wishes,
Margaret

Many thanks to all who offered suggestions. The online resources are fabulous. Alan, the Harry Price Library had completely slipped my mind so I am grateful for that reminder. And Gerhard, while I would love to take a research trip to Freiburg, I'm afraid London is as far afield as I can go for now. I am quite grateful however to you for drawing my attention to your library holdings.

Best wishes and thanks to all,
Alison
