Database Information System DBIS
Scientific discourse proceeds predominantly in journals.
If one is looking for professional articles one has to search in databases. In general these are expensive and provided for the public by research institutes or big libraries who acquire access by purchasing licences. In some cases licences are valid just for one working station, in others for a whole campus net. But there are also databases in the www. where access is free. The database information system DBIS developed by the University Library of Regensburg gives a review about both kinds of databases. Retrieval is possible by either subject or keyword.
