Between them, libraries in the UK hold quite a wide range of US newspapers, so if you can't find things here in Oxford or online, you may well be able to track them down in other libraries. The best starting place is the British Library, and you can search their newspaper catalogues online.
Quite a few other libraries in the UK also have varying collections of US newspapers. The best way to find these is to search COPAC.
