    Abstract
    Considers what elicitation or requests for information search intermediaries make of users with information requests during an information retrieval interaction - including prior to and during an information retrieval interaction - and for what purpose. Reports a study of elicitations during 40 mediated information retrieval interactions. Identifies a total of 1.557 search intermediary elicitations within 15 purpose categories. The elicitation purposes of search intermediaries included requests for information on search terms and strategies, database selection, search procedures, system's outputs and relevance of retrieved items, and users' knowledge and previous information seeking. Investigates the transition sequences from 1 type of search intermediary elicitation to another. Compares these findings with results from a study of end user questions

    Abstract
    The author presents the results of additional analyses of shifts of focus in IR interaction. Results indicate that users and search intermediaries work toward search goals in nonlinear fashion. Twenty interactions between 20 different users and one of four different search intermediaries were examined. Analysis of discourse between the two parties during interactive information retrieval (IR) shows changes in topic occurs, on average, every seven utterances. These twenty interactions included some 9,858 utterances and 1,439 foci. Utterances are defined as any uninterrupted sound, statement, gesture, etc., made by a participant in the discourse dyad. These utterances are segmented by the researcher according to their intentional focus, i.e., the topic on which the conversation between the user and search intermediary focus until the focus changes (i.e., shifts of focus). In all but two of the 20 interactions, the search intermediary initiated a majority of shifts of focus. Six focus categories were observed. These were foci dealing with: documents; evaluation of search results; search strategies; IR system; topic of the search; and information about the user
