eIFL-FOSS advocates free and open source software (FOSS) use in libraries in developing and transition countries. It aims to raise awareness and understanding of FOSS, facilitate eIFL.net member engagement with FOSS development communities, and undertake projects of special significance to eIFL.net members. Working closely with a network of eIFL-FOSS country co-ordinators, the program will build FOSS capacity in libraries; share experiences and expertise; develop support material for evaluation of and migration to a FOSS integrated library system (ILS); and provide a home for the Southern African Greenstone Support Network.
