SOED stand for "New Shorter Oxford English Dictionary". It is a dictionary in two volumes (about 4 000 pages) that is more or less an abridged form of the OED; it is conceived on historical principles: 'it sets out the main meanings and semantic development of words current at any time between 1700 and the present day' ("the present day" being 1993 for my version, year of edition of my copy). Each meaning is labeled with the period of validity, but the origin of the period is the true date, which can go back as far as Old English (roughly 700 to 1100). In addition, this dictionary provides 'a wide range of scientific and technical words such as might be of interest to serious amateurs or advanced students'. My edition, the fourth, called "The New Shorter Oxford Dictionary On Historical Principles", is 'a replacement for the third edition of the "Shorter Oxford English Dictionary", but not a direct revision of its text'. 'The New SOED editors returned to the Oxford English Dictionary itself (in later stages the second edition of 1989, originally the first edition of 1884-1928 and its four volume Supplement of 1972-86), and reabridged, conflated, revised, restructured, added and updated'.
