Collected and edited by Chauncey Brewster Tinker and published in two volumes by the Clarendon Press in 1924, Letters of James Boswell was the first comprehensive scholarly edition of James Boswell's correspondence, assembling 389 numbered letters written between July 1758 and May 1795.

Before Tinker's edition, Boswell's published correspondence consisted chiefly of scattered letters in the Life of Johnson (1791), Letters Between the Honourable Andrew Erskine and James Boswell, Esq. (1763), and the heavily expurgated 1857 edition of Boswell's letters to William Johnson Temple. By collating the surviving Temple autographs in the Pierpont Morgan Library and gathering more than one hundred previously unpublished letters from public archives and private collectors on both sides of the Atlantic, Tinker restored excised passages and brought together Boswell's letters to Temple, Samuel Johnson, Edmond Malone, Sir William Forbes, John Wilkes, David Garrick, Edmund Burke, Jean-Jacques Rousseau, Belle de Zuylen, William Pitt, his estate overseer Andrew Gibb, and others.

The preparation and publication of this edition also played a direct role in the modern rediscovery of the Boswell papers. On July 29, 1920, while seeking manuscripts for the edition, Tinker published a letter in The Times Literary Supplement asking owners of Boswell letters to contact him. The appeal prompted two anonymous communications directing him to Malahide Castle near Dublin, seat of Boswell's great-grandson Lord Talbot de Malahide. Although none of the letters in the 1924 volumes came from Boswell's descendants, the publication of the edition led to Tinker's visit to Malahide Castle in July 1925, where he confirmed the survival of the family archive later acquired by Ralph Heyward Isham and eventually by Yale University (a history chronicled in Frederick A. Pottle's Pride and Negligence and David Buchanan's The Treasure of Auchinleck).

While gradually superseded for individual correspondences by the multi-volume Yale Research Edition of Boswell's correspondence (which includes both sides of the correspondence along with letters later recovered at Malahide Castle and Fettercairn House), Tinker's two-volume edition remains a landmark in Boswellian scholarship.
