In autumn 2013 Graz Public Library launched a currently unique library social project in Austria: volunteer book messengers visit senior and homebound citizens, take along books and other media from the library, spend their time with them in conversation and, if required, read to their clients. "Besuch&Buch" has been inspired by "Die Medienboten", a project started by Hamburg Public Libraries in 2007. This work analyses the three goals of "Besuch&Buch" which are: 1. the enhancement of cultural and 2. social participation of senior citizens and 3. the support of voluntary work with regard to demographic change. The ambition of this master the-sis is to find out if "Besuch&Buch" can be regarded as a best practice example of social library work and a model project for other public libraries in Austria.Guided interviews with 15 book messengers and two expert interviews with the pro-ject managers of "Besuch&Buch" clearly confirmed the research questions with relation to social library work. From a gerontological aspect, face to face interviews with the visited senior and homebound citizens have developed to be a target of further research. A second objective concerns a re-interpretation of “Besuch&Buch” goals. This fact is based on interview outcomes and the mission statement of Austrian public libraries as well. Goals will have to include from a gerontological angle considerations on reading promotion in old age, information disadvantages of older people, the "digital divide", and voluntary work with respect to social exchange.Future research could result in a model concept of social library work for Austrian public libraries, developed by Graz Public Library in a gerontological context.
