The contemporary authorities for Johnson's life, other than Boswell,
are Sir John Hawkins's _Life_, Mrs Piozzi's _Anecdotes_, Fanny Burney's
_Diary_, and anecdotes by many others.
Most of these were collected by the late Dr Birkbeck Hill in his two
volumes of _Johnsonian Miscellanies_ (Oxford, 1897); two volumes of
Johnson's _Letters_ were also published by the same editor in 1892.
Of modern criticism on Johnson the following may be recommended:
Lord Macaulay: _Boswell's Life of Johnson_. 1831.
Article on Johnson in the _Encyclopaedia Britannica_, 1856.
Thomas Carlyle: _Boswell's Life of Johnson_. 1832.
Sir Leslie Stephen: _Samuel Johnson_. (_English Men of Letters_ series.
Macmillan, 1878.)
