Dublin: Thomas Ewing, 1775. First quarto edition and first complete edition printed in Ireland; 2 vols., pp. [70] plus unpaginated lexicon in double column; full contemporary calf, with a neat 20th century rebacking, new red and black morocco labels on gilt-paneled spines; prelims in volume II dampstained, a very good, sound copy of a not-so-common edition, based on the fourth London folio printed in 1773, and the only edition for which Johnson provided any additions or corrections. From his famous prose "advertisement" in vol. I: "Perfection is unattainable, but nearer and nearer approaches may be made; and finding my Dictionary about to be reprinted, I have endeavoured, by a revisal, to make it less reprehensible ... Many faults I have corrected, some superfluities I have taken away, and some deficiencies I have supplied..." Alston V, 184; Courtney 56-7; Fleeman 55.4D/5a; Kennedy 6280.
