In everyday life, many people use the web as a resource for knowledge. In this paper we are investigating the preconditions for a web resource called learning domain. The characteristics of the web resource learning domain can contribute to a reduction of well-known problems with structuring the content in a communicative way and also to contribute to an increased trust of the presented information. In the paper the characteristics of learning domains are described and some examples of web sites with characteristics contiguous to that of a learning domain are discussed. Our conclusions are that web resources with learning domain characteristics can contribute as a knowledge support. The challenge related to learning domains is not a technological one but instead how to arrange the information in such a way that it makes sense for the users.
