English literature -- Scottish authors

The Boswell Collection contains the correspondence, diaries, and manuscripts of author James Boswell; estate records, letters, personal and professional papers, and other materials documenting the lives and careers of ten generations of Boswells and their possession of the barony of Auchinleck; and correspondence relating to the political career of Alexander Bruce, Earl of Kincardine.

The Llewelyn Davies family papers contain correspondence, photographs, and other material relating chiefly to the Llewelyn Davies family, though materials also relate to members of the Du Maurier family and to author and dramatist J. M. Barrie, whose character, "Peter Pan," was inspired by the Llewelyn Davies children.

The collection contains works by and about Ritson, a small quantity of correspondence, and the manuscript of the Bibliographia Scotica.
