In 1933, the title The Oxford English Dictionary fully replaced the former name in all occurrences in its reprinting as 12 volumes with a one-volume supplement. In 1895, the title The Oxford English Dictionary was first used unofficially on the covers of the series, and in 1928 the full dictionary was republished in 10 bound volumes. Work began on the dictionary in 1857, but it was only in 1884 that it began to be published in unbound fascicles as work continued on the project, under the name of A New English Dictionary on Historical Principles Founded Mainly on the Materials Collected by The Philological Society. It traces the historical development of the English language, providing a comprehensive resource to scholars and academic researchers, as well as describing usage in its many variations throughout the world. The Oxford English Dictionary ( OED) is the principal historical dictionary of the English language, published by Oxford University Press (OUP).
