McKerrow's work had three main focuses: • the textual study of early English Drama, especially the works of
Thomas Nashe and
Shakespeare; he was one of the founder members of the
Malone Society. • the history of the English book trade in the early-modern period; he made three substantial contributions in this field: ''Printers' and Publishers' Devices in England and Scotland, 1485–1640
(1913), Title-Page Borders used in England and Scotland, 1485–1640'' (with
F. S. Ferguson) (1932), and under his general editorship the volume for 1557–1640 in the Bibliographical Society's
Dictionaries of the printers and booksellers who were at work in England, Scotland and Ireland, 1557–1775 (1910). • the theory and practice of historical and textual bibliography: firstly, his major edition of the works of Thomas Nash (1904); his
An Introduction to Bibliography for Literary Students (1927) which remains a standard work (supplemented now by
Philip Gaskell's
New Introduction to Bibliography, 1972); and the
Prolegomena for the Oxford Shakespeare (1939) which was intended to be the introduction for a full scientific critical edition of Shakespeare which was unfinished at his death. • With
A. W. Pollard and
W. W. Greg, R.B. McKerrow was one of the three great figures of English bibliography of the first half of the twentieth century. • In 'An Introduction to Bibliography for Literary Students', (1927), on the
Long s question, McKerrow wrote: "Though it would be amusing to do so, there seems to be no reason to accept the legend that
John Bell (publisher) initiated the change, (to the short 'S') in his edition of Shakespeare because of his dismay at the appearance of the long s in Ariel's song in The Tempest: i.e.: "Where the bee sucks, there suck I." ==Selected publications==
