This from the LIS-BAILER list:
A selection of anti-apartheid periodicals published during the period 1960 to 1994 have been digitised by DISA (Digital Imaging of South Africa Project funded by the Andrew Mellon Foundation). The digitised journals have been indexed and are available on the web for research purposes. As most of these journals are not readily available in South African Libraries and complete collections are rare, information managers are encouraged to create links from their Library OPAC to the digitised version on the Disa website by inserting the relevant URL in the SAMARC 856 field. This will greatly enhance user access and availability. The full list of digitised periodicals and the required URLs for the links are available from
