A great bookshop; I used it regularly and still have many of the books I bought there. What I found out recently is that Burne Jones the artist and William Morris the designer and writer used it. Here is a quote from the biography of Burne Jones 'The Last Pre-Raphaelite: Edward Burne-Jones and the Victorian Imagination' by Fiona McCarthy.
The autumn brought a new excitement, the Morte d'Arthur, the book that of all books altered the direction of Burne-Jones and Morris's creative lives. Le Morte d'Arthur was the lengthy cycle of Arthurian legends written by Sir Thomas Malory, a knight from Warwickshire. It appears that he was working on it while he was in prison, charged with the un-knightly crimes of violence, theft and rape. Malory's magnum opus was completed in 1471 and printed by Caxton in 1485. In 1817 Robert Southey, so-called 'Lake poet' and the current Poet Laureate, produced his own edition of Malory and this was the version Burne-Jones had discovered by chance in Cornish's, the bookseller in New Street in Birmingham where the impecunious undergraduate spent many hours each day reading voraciously and buying occasional cheap books to pacify the owner. The Morte d'Arthur was far beyond his means but when Morris came to stay in Birmingham he bought it almost without thinking and, wrote Burne-Jones, 'we feasted on it long'.
