The dictionary was far and away the best of its day, a milestone in English-language lexicography to which all modern dictionaries owe some gratitude

Johnson's dictionary was still considered authoritative until the appearance of the Oxford English Dictionary at the end of the nineteenth century

It draws together many of the previous lexicographical  practices into a more consistent methodology

He applies to the monolingual English dictionary practices which had previously been applied only to bilingual dictionaries, particularly Latin dictionaries, or to technical dictionaries, or to specialised dictionaries such as law dictionaries

His methodology and careful delineation of sense remained a model for subsequent lexicographers even into the twentieth century
