The following article provides a number of additions to Further letters of David Hume, the supplementary edition of Hume’s letters and manuscripts published by the Edinburgh Bibliographical Society in 2014. The article is intended as a provisional resource for scholars who are awaiting a complete Correspondence of David Hume, scheduled for appearance with the Clarendon Edition of the Works of David Hume (Oxford University Press), and it includes several unknown Hume letters and manuscripts which were either inadvertently omitted from Further letters of David Hume or discovered in the period since its publication.
