Lantern slides chiefly of Durham city, particularly Durham castle, mostly (perhaps all) from the collection of the architect W.T. Jones, F.S.A., F.R.I.B.A. (1864-1932), and probably including a number taken by him.
A majority of the slides received via the Archaeology Dept relate to Durham Castle, and a number were apparently made for Jones from negatives of the 1920's restoration work now in the Durham Castle Buildings Archive.
Others relate to other Durham buildings, particularly the cathedral and the town hall, and to Durham personalities and documents. A few are of drawings of medieval siege engines and other weapons, and seem to have been produced for lectures Jones gave on the medieval city and castle. Many bear his WTJ monogram. The slides seem to have been used also by more recent lecturers and to have been considerably disarranged, and possibly also augmented, in the process, so that a few of the slides now present may actually be unconnected with Jones. The group of 28 slides already held by the University library when the Archaeology Department's deposit was received are all of Durham Castle. Most are of high quality, apparently the work of a professional photographer. They are linked to Jones by the subject matter and date (approximately the 1920's), and the inclusion of a slide of the map of the city wall prepared for his article The Walls and Towers of Durham , Durham University Journal , v. 22/23 (1921-23), pp. 241-6, 273-8, 314-7, 357-61, 389-92, and 524-8; the map follows p. 278.
