The Sudan Open Archive offers free digital access to knowledge about all regions of Sudan. It is an expanding, word-searchable, full-text database of historical and contemporary books and documents. The current version, SOA 2.0, incorporates a comprehensive, interactive guide to internet resources on Sudan.

The Sudan Open Archive (SOA) is designed and implemented by the Kenya and UK-based Rift Valley Institute, working with institutional partners in the north and south of Sudan. The Archive was created by DL Consulting using open-source Greenstone archive software developed by the New Zealand Digital Library project at the University of Waikato. It is maintained with support from the J.M. Kaplan Fund. Other partners include UNICEF, UNEP and the Southern Sudan Centre for Census, Statistics and Evaluation.
