this edition - expanded to include the text of letters unavailable at the time of teh volume's first publication in 1969 - records James Boswell's quest over a period of more than 20 years to amplify his knowledge of his major biographical subject, Samuel Johnson, through correspondence with friends, informants and other authorities. The volume, with revised and updated annotation, shows Boswell's struggles through his personal distress to gather material for his "Life of Johnson". It notes many of his revisions of his sources, changes made in manuscript and proof, and revisions of the first and second editions. It also presents letters that illuminate the contemporary reception of his innovative, controversial and influential biography (which first appeared in 1791), taking the story as far as exchanges in 1808 between Boswell's friend and editor, Edmond Malone, and his son, James Boswell the younger, about corrections for the sixth edition of 1811. Throughout, the annotation highlights a range of 18th-century figures, issues and topics.
