- Abstract
- Compares and evaluates the functional capabilities and interface characteristics of OPACs from the user oriented perspective, using a systematic framework. OPACs of OhioLINK and its 16 member libraries are the object of the investigation. The interfaces used 6 system software but showed a variety of features in access to OPACs, operational control, access points, search formulation control, and user assistance. Interface design alternatives are identified and qualitatively analyzed
