    Abstract
    Identifies and characterizes the knowledge used by experienced librarians while searching for subject information in online catalogues. 10 experienced librarians performed the same set of 6 subject searches in an online catalogue. Investigates the knowledge used to solve retrieval problems. This knowledge presents expertise in the use of the catalogue. Data were collected through the use of think aloud protocols, transaction logs and structured interviews. Knowledge was defined as knowledge objects (factual knowledge), knowledge of events (experimental knowlegde), knowledge of performance (process knowledge), and metaknowledge. Metaknowledge is the sense of whole derived from the integration of factual, process, and experimental knowledge about the search and the conditions under which it is performed. Focuses on metaknowledge. For evidence of metaknowledge the data were examined for explanations that participants gave for their actions and observations, and for ways that participants evaluated their own progress during the process of searching. Reasons and explanations given by searchers were related to all phases of the library information retrieval process from the user's receipt of material to policies for collection development, and not just events directly related to the performance of a particular search task

    Abstract
    The research described in this article extends work done on human behavior in naming concepts and objects by adapting a methodology developed at Bell Labs and applying it to a library indexing language, the Library of Congress Subject Headings. The study investigated the representation of users' knowledge (names of objects and concepts), database representation for similar objects and concepts, and degree of agreement among users and between users and information systems. Three user groups give names to 40 stumuli. Names generated were compared with each other and with LCSH. Degree of agreement was calculated using similarity measures. The analyses identified patterns of agreement and variability in naming. There was little agreement in the names people use and the names recommended for use by LC, implying that retrieval systems should do more to accomodate common naming behavior

    Abstract
    The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.

    Abstract
    Representation and retrieval obstacles within a digital library designed for use by middle school children are presented. Representation of objects is key to retrieval. Tools used to create representations for children's resources, such as controlled vocabularies, need to be more age appropriate. Development of age-appropriate controlled vocabularies requires us to learn more about the ways children interact with systems and form search strategies to represent their information needs. Children's search terms and questions are a rich resource for learning more about their information seeking process, their question state, and their formulation of searches. A method for gathering and using children's own search terms and the benefits of their utilization in developing more age-appropriate controlled vocabularies are discussed.

    Abstract
    Anfang 1994 eröffnete die SWB-Verbundzentrale einen TELNET-Recherchezugang für Endnutzer zur SWB-Datenbank. Damit bot sich zugleich die Möglichkeit, ein Feedback über die Recherchebedürfnisse und -strategien von Endnutzern zu erhalten: zum einen durch eine statistische Erfassung der Nutzerrecherchen über einen Zeitraum von 7 Monaten, zum anderen durch auswertung von E-Mail- Nachrichten der Endnutzer mit Stellungnahmen zur angebotenen Rechercheschnittstelle. Die Ergebnisse der Untersuchung werden unter dem Gesichtspunkt vorgestellt, welche Vorgaben sich aus ihnen für die Gestaltung einer geplanten WWW-Recherche-Oberfläche für die SWB-Verbunddatenbank ableiten lassen
