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". 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 ten bound volumes. In 1933, the title "The Oxford English Dictionary" fully replaced the former name in all occurrences in its reprinting as twelve volumes with a one-volume supplement. More supplements came over the years until 1989, when the second edition was published, comprising 21,728 pages in 20 volumes. Since 2000, compilation of a third edition of the dictionary has been underway, approximately half of which was complete .
