The aim of the article is to present virtual campus model and case studies of various type virtual campuses as virtual organisations enabling to start and develop e-learning process at the particular colleges and their groups. The article consists of four parts. The first one presents the benefits of starting virtual campus concept. Part two is the presentation and evaluation of e-campus models called: College, Partnership, Concern and Portal. In the first part we present precise analysis of all four models prepared by the research groups participating in projects financed by the European Union. There is also the virtual campus concept integrated with the traditional education system and supporting mobility - bimodal with virtual mobility. The conditions concerning effective e-campus model implementation are presented in the third part of the article. The last part contains case studies related to the presented models, conditions and functional abilities. The article is based on the analysis of reports on virtual campuses prepared by the research groups founded by European Union and on analysis of existing e-campuses. The authors participated in building one of them - the Baltic Sea Virtual Campus (BSVC). The research of existing models and their implementation enabled the authors to create their own virtual campus model - a bimodal one with virtual mobility.
