A new chapter in an author's feud with Oxford University Press began when philosopher Andrew Malcolm opened a bookshop to taunt the university.

Mr Malcolm was left with a £12,500 legal bill at the end of a six-year legal battle with OUP that began when the company declined to publish his book.

Not satisfied with writing a 250-page book about the legal saga he has now opened his own bookshop on Broad Street to sell it.

The window of the shop, opposite Balliol College, is filled with posters bitterly criticising the university over his treatment.

Inside, the walls are adorned with enlarged newspaper stories about the case, together with recent stories which have embarrassed the university.

Oxford's latest bookshop, which Mr Malcolm has taken on a short-term lease, has just two books in stock: The Remedy, the account of the trial, and Making Names, the 200,000-word Platonic dialogue that the OUP declined to publish back in 1984.

He sued OUP for breach of contract, saying that they had given him a verbal agreement to publish. He lost in the High Court, which found he had a "strong moral though not legal commitment", then went to appeal. Later he returned to the High Court, unsuccessfully arguing that the university agreement not to publish derogatory remarks about his book had been breached.
