The SOED is an abridged version of the larger OED, containing words in use since 1700. In two volumes it is easier to use than the full OED for general queries; the answer sought is less likely to be buried in a lengthy entry. Also, being shorter has allowed the editors to completely update the dictionary over the different editions, meaning it often reflects new scholarship that has yet to be added to its larger cousin.
