The increasing use of information technology (IT) has changed our way of dealing with information. On the one hand IT offers us new ways of creating, using, and making available information and on the other hand it also requires new approaches just because of that, and because of the different nature of digital information. Nonetheless to date a huge mass of digital information resources is available e.g. on the world wide web, and is growing every minute. Accessibility in this respect is a crucial feature of this digital information. How can that be achieved and above all maintained? To what extent are traditional tools and approaches still sufficient? That are questions that many organisations are facing to date.
