A fourth volume, issued in 1763, is regarded by Sir Leslie Stephen as of doubtful authenticity.
James Dallaway, in 1803, brought out an enlarged collection and added to it the poems, and a second edition, with some new letters, appeared fourteen years later.

Lady Mary's great-grandson, Lord Wharncliffe, edited the correspondence in 1837, and this, revised by Mr.Moy Thomas, was reprinted in 1861 and again in 1887.
There have been published selections from the correspondence by Mr.A.R.
Ropes (1892) and by Mr.Hannaford Bennett (1923).
The principal authorities for the life of Lady Mary Wortley Montagu are the Memoirs of James Dallaway prefixed to an edition of the _Works_ (1803) and the _Introductory Anecdotes_ in a new edition (1837) by Lady Louisa Stuart, the daughter of Lady Bute and the granddaughter of Lady Mary.

There is another account of Lady Mary by the late Moy Thomas in revised editions of the letters and writings (1861 and 1887).

Sir Leslie Stephen was responsible for the memoir in the _Dictionary of National Biography_.

In 1907 appeared _Lady Mary Wortley Montagu and her Times_, by that sound authority on the eighteenth century, "George Paston," who was so fortunate as to discover many scores of letters hitherto unpublished.
Other sources of information are to be found in Pope's Correspondence, Spence's _Anecdotes_, Dilke's _Papers of a Critic,_ Cobbetts _Memorials of Twickenham_, the Stuart MSS.
