    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

    Abstract
    This paper reports on usability evaluation that was carried out to evaluate the LRM-based prototype interface, presented in Part 1. A combination of focus group, Wizard of Oz method, and think-aloud protocol was used. The study was conducted in May 2019 with seven Slovenian catalogers from Maribor Public Library. Although participants had some difficulties understanding the LRM model, the user interface proved to be quite easy to use, quick to understand, and transparent. The functionality of the proposed prototype proved to be adequate, since the catalogers successfully and independently completed all the tasks without major problems and errors.
