This collection consists of architectural drawings and blueprints, primarily elevations and plans reconstructing ancient sites and buildings, notes, photographic materials, photocopies and correspondence relating to the work of Sheila Gibson (1920-2002), who established a longstanding collaboration with the British School at Rome as scholar first, and then as a collaborator during John Bryan Ward-Perkins' directorship. Even after her collaboration with John Bryan Ward-Perkins, she continued to work for Amanda Claridge (Castelporziano Project), Richard Hodeges (San Vincenzo al Volturno) and Bryan Ward-Perkins (Leonine Walls). The items acquired by the BSR concern excavations and projects in Italy and North Africa. Correspondence mostly relates to the organisation of the exhibition 'The work of Sheila Gibson, R.I.B.A., A.A., Dip (Hons), F.S.A.' held both in London and Rome in 1991. Sheila Gibson developed a precise methodology that allowed her to identify the horizontal and vertical lines of the architectural structures of the ruins and reproduce them on paper accurately, eliminating what was irrelevant from the drawing and providing the archaeologists with a realistic idea of the building in the archaeological excavation.

New material added 2024-03-01: blueprints of Sheila Gibson's drawings for the Triclinium of the Domus Flavia on the Palatine (1964, revised in 1984-85), deposited by Janet DeLaine at the BSR. Janet De Laine helped survey the vestibule's walls and added the numbers annotated on these blueprints.
