    Notes: Purpose - This paper proposes solutions to problems related to the maintenance and update of already existing e-learning courseware. Design/methodology/approach - A structured approach in form of a reference model for the re-engineering of existing educational material is presented. In this context, concepts already established in the area of aspect-oriented programming are applied to deal with crosscutting concerns in e-learning material. Finally, a software product line approach is proposed for the creation of new courseware using re-engineered components. Findings - It turns out that some aspects of the methodology developed for aspect-oriented programming can also be used to restructure the existing e-learning material in such a way that maintenance is eased and redundancy is significantly reduced. In addition, software product lines for e-learning material provide a global framework for coordinating the re-engineering and reuse of components. Practical implications - The advantage of the proposed approach is that existing e-learning standards and systems do not have to be modified or adapted. Originality/value - Usually, courseware evolves during a longer period of time and its development does not start every time from zero. There is a high incentive for re-engineering of existing courseware, since it constitutes in many cases the competitive advantage of companies or universities. However, up to now, little attention is paid to the maintenance and the efficient update of e-learning material which is already there.

    Description / Table of Contents: Summary Reference databases and electronic fulltext documents are important pillars on which knowledge acquisition for IT professionals rests on. Searching the Internet can play a supplementary role only. The database CompuScience is a fulcrum for knowledge in our field and needs to be extended. Recent trials by libraries with electronic fulltext documents are quite promising. This may, in the long run, change user attitudes. Solutions should be supported and services introduced now that students and practitioners can rely on. Computer scientists are interested and obliged to develop creative concepts and to provide technical leadership in this area.
    Notes: Zusammenfassung Literatur-Nachweis-Datenbanken und elektronischer Volltext sind wichtige Säulen, auf denen die Wissensversorgung der in der Informatik tätigen Fachleute ruht. Die offene Suche im Internet kann hier nur eine unterstützende Rolle spielen. In der Datenbank CompuScience hat die Informatik eine Drehscheibe der Wissensversorgung, die es auszubauen gilt. Bezüglich der elektronischen Volltext-Versorgung durch überregionale Bibliotheken gibt es erste Erfolg versprechende Versuche, die zu langfristigen Veränderungen im Nutzerverhalten führen können. Es geht jetzt darum, Lösungen zu unterstützen und Dienstleistungen einzuführen, auf die sich Studierende und die im Beruf tätigen Fachleute verlassen können. Die Informatik hat ein Interesse und eine Verpflichtung, kreative Konzepte zu entwickeln und ihre Vorreiterrolle auf diesem Gebiet weiter wahrzunehmen.
