    Abstract
    The proliferation of electronic databases and reduced library collections require researchers to be familiar with an increasing range of bibliographical resources. To assist users in searching multiple databases the PICA network in the Netherlands has developed PiCarta as a single information source. The servie enables users to access bibliographical databases and electronic journals using Boolean logic, fuzzy operators, and subject weighting. The system is, however, dependent upon indexing methods used in original sources

    Abstract
    In 1997 a survey was held in the Netherlands by the Innovatie Wetenschappelijke Informatievoorziening (Innovation in Scientific Information Services) Steering Group to establish how much use students and research workers make of the Internet. 84% of respondents reported it useful for email communication, whilst 49% used it for consulting web documents. However, only 27% of respondents used it to consult electronic journals. A majority of respondents asked for greater assistance from library staff
