Lantern slides, 35mm slides, negatives, glass plate negatives, and indexes to slides. Also one box of 5 unexposed AGFA-Gevaert brand negatives. Wooden cabinet originally used to house lantern slides retained separately.

A combination of original and published sets of slides. Initially glass lantern slides, later additions were acquired in 35mm slide format with some lantern slides then reformatted. The collection also appears to include some slides obtained from other Departments.

In 1950, the St Lucia campus Parnell Building lecture theatres were designed specifically without windows to facilitate the use of slide projectors.
