    Abstract
    In order to test the power of metadata on information retrieval, an experiment was designed and conducted on a group of 7 graduate students using the Dublin Core as the cataloguing metadata. Results show that, on average, the retrieval error rate is only 2.9 per cent for the MES system (http://140.136.85.194), which utilizes the Dublin Core to describe the documents on the World Wide Web, in contrast to 20.7 per cent for the 7 famous search engines including HOTBOT, GAIS, LYCOS, EXCITE, INFOSEEK, YAHOO, and OCTOPUS. The very low error rate indicates that the users can use the information of the Dublin Core to decide whether to retrieve the documents or not

    Abstract
    Describes a study in which 6505 papers from 23 Chinese scientific and technical journals published in the 7 years from 1990 to 1996 were investigated. The quantity, languages and types of citations were analyzed and compared with data from the 1970s. In this way the progress of citations for Chinese scientific and technical journal literature can be seen
