The standard edition of Johnson’s verse is the sixth volume of the Yale Edition of the Works of Samuel Johnson: Poems, ed. E. L. McAdam, Jr., and George Milne (New Haven and London: Yale UP, 1964).
The texts used are based on Douglas Grant's Reynard Library edition (Hart-Davis, 1952). The specific edition used by Professor Grant is given for each work here. The spelling has been modernized, but not the punctuation. Note that the punctuation is generally rhetorical rather than syntactical.
The standard edition of Drayton's works is by J. W. Hebel, K. Tillotson, and B. H. Newdigate (5 vols.; Oxford: Blackwell, 1931-41). The Poems are edited by E. J. M. Buxton ("Muses' Library" 2 vols., London: Routledge and Kegan Paul, 1953).
