Since the 1990’s Open Access has developed into an alternative model for scientific publication. Today an increasing political interest in promoting Open Access is commonly channeled through the implementation of policies by research funders. However, in the scientific community the uptake and acceptance of the model has been of notably different character.This Master’s thesis examines the understanding of and attitudes towards open access among eight senior Swedish researchers and how these have been affected by the implementation of the Swedish Research Council’s Open Access-policy as implemented in 2010. It further asks the question of how researchers’ publishing practices can be understood as shaped by and performed within actor-network configurations. The study is based on interviews with researchers from three academic disciplines. The empirical material has been analyzed through the perspective of actor-network theory.The study finds that the impact of the Swedish Research Council’s policy has been low. Yet, perceived as a floating object, the policy has forced the researchers to adhere to and position themselves in relation to the immanent powers of the policy and, thus, to Open Access both as movement and publishing model. The study also finds that both the traditional model for scientific publishing and the Open Access model can be understood as actor-networks, currently competing for the researchers’ loyalty and involvement in order to secure future dominance. The study finally concludes that in order to fully understand researchers’ practices and attitudes it is necessary to perceive these as shaped in and by extra-social contexts and forces. / Program: Masterutbildning: Digitala tjänster - kultur, information & kommunikation
