Caxton's purpose was to _______.

William Caxton introduced the art of printing into
England in a remarkably short span of time. His
considerable success as a merchant enabled him to
retire early and devote himself to the literary pursuits
he loved so well. He set up his printing press at
Westminster, where he published nearly a hundred
books in the remaining fourteen years of his life.
Caxton did not confine himself to printing. Besides
his almost incessant labours at the press, he
translated as many as twenty books himself. What is
even more important, is that he published books in
English at a time when most authors' works
appeared in French or Latin. Caxton deliberately
made it his aim to hasten the spread of knowledge by
making books available to the public in English.
