Looking for a suitable home for this archive of South African newspapers

We would like to donate my grandfather's archive to a suitable organisation. He collected and recorded every South African paper (English and Afrikaans) from 1860 as a part of his company Microfile. Here is a link to an article about his business in De Gruyter magazine.

If anyone would be interested in receiving this donation please email humphrey.curtis@kcl.ac.uk
