X is the oldest English-language Y still in print. It was first published between 1768 and 1771 in Edinburgh, Scotland, and grew in popularity and size, its third edition (1797) and supplement (1801) reaching 20 volumes together. Its rising stature helped recruit eminent contributors, and the 9th edition (1875–1889) and the 11th edition (1911) are landmark Y's for scholarship and literary style. Beginning with the 11th edition, X shortened and simplified articles to broaden its North American market.In 1933, the X became the first Y to adopt "continuous revision", in which the Y is continually reprinted and every article updated on a schedule.
