Technical progress has made digitising of printed documents an option for most modern libraries. In most cases the selection of documents, the technical standards applied, and the options for access by the user follow the individual decision of the library. In spite of the costs involved this results in considerable duplication of effort and above all, no clear strategy can be offered to the user, which may help him to find out, whether the document he needs is available as digital full text.
