In November 1954, a memorial to Caxton was unveiled in Westminster Abbey by J. J. Astor, chairman of the Press Council. The white stone plaque is on the wall next to the door to Poets' Corner. The inscription reads:
Caxton is credited with standardising the English language through printing—that is, homogenising regional dialects and largely adopting the London dialect. This facilitated the expansion of English vocabulary, the regularisation of inflection and syntax, and a widening gap between the spoken and the written word. Richard Pynson started printing in London in 1491 or 1492 and favoured what came to be called Chancery Standard, largely based on the London dialect. Pynson was a more accomplished Stylist than Caxton and consequently pushed the English language further toward standardisation.
