The Archives of James Boswell, at Yale University, form one of the most important collections of 18th-century personal papers known to exist. The archives are published in two editions. The Trade Edition contains selected materials from Boswell's private diaries, supplemented by letters, memoranda, and other documents. The Research Edition, annotated for a scholarly readership, includes Boswell's correspondence, complete private journals and notes, the Manuscript Edition of the Life of Johnson, and a three-volume analytical catalogue of the collection.
