The aim of this Master’s thesis is to examine how librarians, information specialists and teachers discuss Wikipedia within national (Swedish) professional journals. Questions asked in the study are: How is Wikipedia perceived in the professional journals? What different positions do writers and commentators take in relation to Wikipedia? 133 articles from 31 different professional journals in the period from 2001 to the middle of 2010 were analysed. The theory and method used is Laclau’s and Mouffe’s discourse theory from which we created our own model with sex different steps. The results show that there are several recurring discussions, for example about the credibility of user generated content. Another example is the discussion about the use of Wikipedia within the education and school contexts and whether the encyclopedia should be seen as sufficiently credible to use in these contexts. From these discussions we have identified three discourses that we have chosen to call: the knowledge-liberal discourse, the knowledge-conservative discourse and the pedagogical discourse. / Program: Bibliotekarie
