The university started printing books around 1480. It soon grew into a major printer of Bibles, prayer books, and scholarly works. It began what later became the "Oxford English Dictionary" in the late 19th century. Over the last hundred years, Oxford has grown and now publishes children's books, school text books, music, journals, the World's Classics series, a best-selling range of English Language Teaching texts, as well as its academic and religious titles. It opened its first international office in New York in 1896. Changes caused by computer technology and the need to lower costs, led to the Press contracting out its printing and binding work. The Press's printing house at Oxford was closed in 1989. Its former paper mill at Wolvercote was demolished in 2004.
