Based on the large volume of digital information and the heterogeneity in the production, media, and devices that facilitate access, the article highlights some of the problems of digital information as well as the main initiatives that seek to address the problem of preservation.
The Digital Doorway is a joint initiative between the Meraka Institute of the Council for Scientific and Industrial Research (CSIR) and South Africa’s Department of Science and Technology (DST), with a vision of making a fundamental difference to computer literacy and associated skills in the South African population. Underpinning the project is the idea of people’s inherent cognitive ability to teach themselves computer skills with minimal external intervention. For this to happen, computers must be easily accessible to potential learners in an environment conducive to experimentation. Given the low percentage of communities in disadvantaged areas in South Africa with access to computer infrastructure, Digital Doorways are installed in communities where the need is greatest. The systems are extremely robust and employ open source con...
This master thesis deals with the issue of digital piracy of music and film in the internet from a broad perspective. This includes the social, technical, legal and economic perspective with a focus on the latter.

Repositories must be sustainable, trusted, well-supported and well-managed in order to function properly.
