In a small local survey the PSLI was evaluated at Sussex University. The variety in make and specification of hardware/software can cause installation problems, that could raise the cost. Personal contact and printed journals are still the major sources of information for researchers. When they do use electronic sources they want to be able to target their efforts effectively on a good quantity of relevant information in a readily accessible form. Since PLSI does not yet offer this facility, its usefulness is perceived to be limited.
