How was the increase in demand for books met in Europe in the fourteenth century?

the expanded demand for books in Europe was met in the following ways:
(i) Booksellers all over Europe began exporting books to many different countries.
(ii) Book fairs were held at different places.
(iii) Production of handwritten manuscripts also continued to meet the expanded demand. Skilled handwrites were employed by booksellers. sometimes more than 50 scribes were employed bookseller.
(iv) Woodblock printing was widely used to meet the demand.
But in spite of the above efforts, there was still a great need for even quicker and cheaper reproduction of texts which was fulfilled by the development of the printing press by Johann Gutenberg in the 1430s.
