Abstract
eLearning systems have become a very important part of teaching, both as web-based systems for online education and as auxiliary tools for face-to-face study, where they provide an additional learning support for on-campus learners. To insure the sustainability of an eLearning system on both individual and social levels, we have to cover many aspects of sustainability requirements: human, technical, economic, and environmental. This paper provides a systematic literature review of the sustainability meta-requirements for eLearning systems to identify open problems and to present the state of the art of this research area. We analysed 124 papers, so we identified 18 high-level sustainability requirements for eLearning systems.
