It is therefore easy to establish whether this network belongs to an ISP or the request is from an institutional network. The model adopted by Sociological Research Online is as perfect a solution as could be envisaged. One criticism levelled by a librarian was that there is no provision for an academic from a subscribing institution on sabbatical leave at a non-subscribing institution to gain access to the journal. Although print journals suffer this problem, Sociological Research Online does not. It should be possible for a wandering academic to log into their own institutional network from anywhere in the world using Telnet and then access the journal with a browser such as Lynx.
Any limitation is in the capability of the individual reader rather than the technology.
The model satisfies distant learners and homeworkers who can either dial-up through their university network and, if subscribed, will be granted access or can register their ISP and gain free access through that route. Agents Most of the problems associated with the practical side of the subscription system arise from subscription agents. Most libraries place all their journal and book orders through one or two agents who ensure that all orders are fulfilled, and subscriptions are properly established. Not all agents are yet experienced in handling electronic-only material. The agent should have been able to spot this error while they were processing the order.
