n order to use the online catalogue efficiently the librarian has been trained how to work with it – how to insert new media and delete old media in the back end. Also the users needed to get familiar with the online catalogue. Whereas teenagers and young adults use the online catalogue intuitively, young children and elderly peope need additional guidance. Therefore a video tutorial has been created guiding the user through the steps of searching media in the catalogue. In addition the librarian offers individual training especially for elderly people and includes this training into the general library introduction for young school children. The video tutorial (in German language) can be found under the following link:
