Is Thornton's Bookshop still at Walnut Court in Faringdon?
How about the White Horse Bookshop on Marlborough Street? If you've visited both, which do you recommend?

i used to visit thorton regularly until it closed down in 2002. name any book and you could find it over there. but i think they are still in busines and use internet and mail orders for the same.

havent been to white horse , so cant comment on it.
