This report examines the possibilities, problems, costs, and benefits of providing online access to the database of the European Documentation and Information System for Education (EUDISED), which is in machine-readable form, but generally available only through the EUDISED R&D Bulletin. The likely nature of such online access is described, including searchable fields and the use of descriptors from the 5-language EUDISED Thesaurus. Three alternative types of arrangements between online systems and database suppliers are discussed, and probable costs for both the Council of Europe and the individual researcher are indicated. Benefits are discussed in terms of the individual researcher, national agencies, and the Council of Europe. It is recommended that the database be made available online if favorable financial terms can be found, and options open to the Council for converting the bibliographic database of the Documentation Centre into machine-readable form are briefly discussed. Appendices include a list of the contents of the EUDISED magnetic tapes, and additional information on the geographical accessibility of online systems, costs for mounting the EUDISED database on BRS and on Lockheed, telecommunications charges, and the availability of other databases on online systems.
