    Abstract
    Experiences with retrieval in OPACs suggest that there are major problems for the users of such systems, such as choosing the 'correct' subject access vocabulary, narrowing or broadening the set of items retrieved regarding the search interest. Such problems relate to two facts: (1) that in the early OPACs subject access has not been considered seriously enough and (2) that the complexity of the topic has not been really recognized. Using a typology of users' questions it is demonstrated which requirements musts be met by a successful online subject access. Improvements of subject access tools are primarily aimed at, pinpointing the interplay between the different subcomponents of any subject facility: a) the features of the indexing languages used; b) the indexing principles used; c) the design and structuring of the database; and d) the possibilities of the technical retrieval facility, the search mode, and query languages. The contribution summarizes the manifold interactions between the four subcomponents listed. Any successful retrieval will heavily depend on the design of these components considering their interactions.

    Abstract
    This study examined how searchers interact with a web-based, faceted library catalog when conducting exploratory searches. It applied multiple methods, including eye tracking and stimulated recall interviews, to investigate important aspects of faceted search interface use, specifically: (a) searcher gaze behavior-what components of the interface searchers look at; (b) how gaze behavior differs when training is and is not provided; (c) how gaze behavior changes as searchers become familiar with the interface; and (d) how gaze behavior differs depending on the stage of the search process. The results confirm previous findings that facets account for approximately 10-30% of interface use. They show that providing a 60-second video demonstration increased searcher use of facets. However, searcher use of the facets did not evolve during the study session, which suggests that searchers may not, on their own, rapidly apply the faceted interfaces. The findings also suggest that searcher use of interface elements varied by the stage of their search during the session, with higher use of facets during decision-making stages. These findings will be of interest to librarians and interface designers who wish to maximize the value of faceted searching for patrons, as well as to researchers who study search behavior.
