In this special issue, we feature selected papers from the 2013 South African Institute of Computer Scientists and Information Technologists Research (SAICSIT 2013) conference, hosted by Rhodes University at the Blue Lagoon Hotel in East London, 7-9 October. The authors of seven of the best SAICSIT papers were invited to submit extended versions of their research for this Special Issue. A second round of reviewing resulted in the four papers published here; two from Computer Science and two from Information Systems.
