Neustart für Bibliotheken ins Informationszeitalter

Abstract

With the success of Google and other internet technologies at the beginning of the information age we recognize a change in the behaviour of scientists and students which implies a radical shift for libraries and information suppliers concerning the use of Google Scholar or Google Book Search. This article deals with the technical background for the success of this special method of information retrieval: full text indexing and citation ranking as special variations of information mining. Discussed are the strengths and weaknesses of the Google solution. The author is also discussing the question under which conditions it would be possible to develop a retrieval strategy which would be competitive with Google Scholar and Google Book Search in the landscape of libraries and union catalogues. The idea is that this will be possible by using the open source index machine Lucene and the web robot nutch. By the use of these technologies libraries are able to develop services for digital and locally available resources, which are similar to those existing within the visible web. One hopes that on the basis of these developments users will not only remain in the internet world - as a recently published study of the OCLC indicated - but also will find attractive solutions offered by their local libraries.
