    Abstract
    Presents a brief report on a study, carried out by the Centre for Interactive Systems Research, City University, to investigate the techniques used for evaluating OPACs: to explore and assess different data gathering methods in studying information seeking behaviour at the on-line catalogue; and to examine how a transaction logging facility could be enhanced to serve as a more effective diagnostic tool.

    Abstract
    Reports the results of a questionnaire survey of 414 libraries in 4 categories: academic libraries; school libraries; public libraries and special libraries; to assess the status of library training initiatives with respect to the libraries' OPACs. Answers were sought to 3 questions: how have libraries modifoed OPAC software; have libraries developed any instructional methods for teaching the use of OPACs; and to what extent are online catalogues self instructional? Results show that most participants' libraries have modofied library OPAC software; librarians continue to teach use of the online catalogue, depending heavily on handouts; few systems have built-in tutorials for users; and very fes have developed computer assisted instruction for the OPAC

    Abstract
    An increasing number of library user studies are employing ethnographic techniques as an alternative to more traditional qualitative methods such as surveys. Such techniques, however, are only beginning to see significant application to catalog user studies. Beginning with a discussion of the applied ethnographic method and its current usage within the field of Library and Information Science research, this article will assess methods that have traditionally been applied to studies of catalog users and present the case for the potential of an ethnographic approach for future catalog evaluation and design.

    Abstract
    Subject access to bibliographic data supported by knowledge organization systems, such as subject headings and classification, plays an important role in ensuring the quality of library catalogues. It is generally acknowledged that users have a strong affinity to subject browsing and searching and are inclined tofollow meaningful links between resources. Research studies, however, show that library OPACs are not designed to support or make good use of subject indexes and their underlying semantic structure. A project entitled OPAC semantici was initiated in 2003 by a number of Italian subject specialists and the Italian "Research Group on Subject Indexing" (GRIS) with a goal to analyse and evaluate subject access in Italian library catalogues through a survey of 150 OPACs. Applying the same methodology, a follow-up survey to assess whether any improvement had taken place was conducted five years later, in spring 2008. Analysis of these two surveys indicated that there was a slight improvement. The authors discuss the results of these two surveys, analyse the problems in subject searching in OPACs and explain the recommendations for subject searching enhancement put forward by GRIS. Using the example of Italian OPACs, the authors will attempt to outline some requirements for a subject searching interface and explain how this can be achieved through authority control.

    Abstract
    This research investigates how people's perceptions of information retrieval (IR) systems, their perceptions of search tasks, and their perceptions of self-efficacy influence the amount of invested mental effort (AIME) they put into using two different IR systems: a Web search engine and a library system. It also explores the impact of mental effort on an end user's search experience. To assess AIME in online searching, two experiments were conducted using these methods: Experiment 1 relied on self-reports and Experiment 2 employed the dual-task technique. In both experiments, data were collected through search transaction logs, a pre-search background questionnaire, a post-search questionnaire and an interview. Important findings are these: (1) subjects invested greater mental effort searching a library system than searching the Web; (2) subjects put little effort into Web searching because of their high sense of self-efficacy in their searching ability and their perception of the easiness of the Web; (3) subjects did not recognize that putting mental effort into searching was something needed to improve the search results; and (4) data collected from multiple sources proved to be effective for assessing mental effort in online searching.
