Liddell & Scott's Greek-English Lexicon (9/e 1940) is used by every student of ancient Greek in the English-speaking world, and covers every surviving ancient Greek author and text discovered up to 1940. In 1968 the Lexicon was updated with a Supplement, which has now, after 13 years' painstaking work, been completely revised and updated.
The ultimate compression of scholarship is the newly revised Greek-English Lexicon and its supplement.
