In the research institutes such as universities or companies, they contract electronic journals for document retrieval and document collection. When an organization contracts electronic journals, the site license is preferred. Because of terms of a site license include location or affiliation of users, available electronic journals differ from users. On the other hand, the user and the terminal are authenticated when the terminal was connected to the network, so an illegal user is excluded, and the terminal is able to connect to a VLAN that had been allocated by dynamic VLAN. With dynamic VLAN, the user can connect to the same VLAN everywhere. However, in such network environment, it cannot be determined where a user accessed by the IP address of the user's terminal, and it is not able to warrant the terms of the site license. In this paper, we propose a network system that adjusts to the site license of electronic journals in the location free network.
