    Abstract
    Examines and compares the use of the Internet among various sectors of the faculty at the Hebrew University of Jerusalem, Israel, in order to verify the influence of a number of parameters on this use. Questionnaires were sent to faculty members in all departments and professional schools of the Hebrew University of Jerusalem, a total population of 918 for both the pilot project and the main study. Results indicated that Internet use is consistently higher among faculty members in the sciences and agriculture than among those in the humanities or social sciences. Makes suggestions for training the level of Internet use among the various disciplines of the faculty

    Abstract
    Investigates the retrieval capabilities of 6 Internet search engines on a simple query. Existing work on search engine evaluation considers only the first 10 or 20 results returned by the search engine. In this work, all documents that the search engine pointed at were retrieved and thoroughly examined. Thus the precision of the whole retrieval process could be calculated, the overlap between the results of the engines studied, and an estimate on the recall of the searches given. The precision of the engines is high, recall is very low and the overlap is minimal
