The Humphreys collection includes historical photographs concerning mining, the Anglo Boer War, early Johannesburg, amongst others. Most of the photographs formed part of Humphreys Collection of Africana. The photographs were given to Historical Papers by the Gubbins Africana Library in 1999, and have been added to the existing Humphreys collection of papers. There are loose photographs, albums, images on glass, filmstrips, postcards, and negatives on film and on glass.

The photographs have been sorted and most are stored with the photographic collections, unless indicated otherwise. Some duplicates and some photographs of limited interest have been grouped in their categories and stored with the original collection of papers.

The photographs taken by the Barnett brothers are Copyright 'The Star' newspaper.

The recordings were made of the last surviving fluent speakers of two major South African Khoisan linguistic families, the Khoekoe (Khoi) and the !Kwi (San). Many of the original recordings on the shellac records were made in the Phonetics Laboratory of the University in 1936, when a group of Bushmen visited Johannesburg for the Empire Exhibition. The recordings on the 33rpm record was made some 18 years later. The recordings were later archived on optical discs with manual enhancement. More description about the project, comments about the recordings and the Khoisan languages, can be found in the booklet which accompanied the CD, produced by Professor Anthony Traill and the Department of Linguistic, Wits University.
