The November 1991 Word Ways exhibited a nine-square by Eric Albert with all of its words contained in a single dictionary (Webster's Second Unabridged), the first one of its kind to be discovered. Can this feat be duplicated with words only from the Oxford English Dictionary? At least two logologists have tried, with varying degrees of success. In the February 1997 Word Ways Richard Sabey presented the first square given below, claiming that it consisted entirely of OED words.
