E-literature in the frame of e-learning

In last two/three decades, advancement in modern information and communication technology enabled e-learning. E-learning is supported with modern information and communication technology. A shift in learning paradigm, from traditional （i.e. collocated participants） to more distance education （i.e. geographic dispersed participants）, especially in the form of e-learning, has resulted in changes in many fields. Traditional and e-learning processes differ significantly in many aspects. One among the most important is the field of literature （e.g. its design, creation, implementation, distribution）. Literature which is used in traditional education process （e.g. hard copy books） could also be used in e-learning process, but is lees suitable. Therefore e-literature has evolved and gained importance recently. E-literature is more convenient because it is in electronic version （not hard copy）, which allows fast and cheap distribution to participants in e-learning process. In the contribution, we research student＇s preferences about literature in e-learning and especially what are the characteristics of a good e-literature. Therefore the paper provides an insight into student＇s attitudes towards the usage of e-literature, which are in turn importantly dependent upon the quality （i.e. characteristics） of e-literature. Results of a research among undergraduate students at business school are presented.
