The James Copland Thorn Papers comprise of a compilation of Thorn's own observational drawings and notes, and (most prominently) copies of archive material which Thorn used for research in support of his publication 'The Necropolis of Cyrene: Two Hundred Years of Exploration' (2005). Many of the series within the fonds are connected to Alan Rowe, who led the original 1952–7 excavations from the University of Manchester, and whom Thorn chooses as his main focal point of analysis in his publication. This material has been collated by Thorn through means of contact with key individuals and/or museums associated.
D26 also contains additional information, notes, illustrations and photographs relating to the historiography of the excavations in Cyrene, and provides a record of Thorn's research methodology, alongside the progression of his thesis.
