The purpose of this study is to examine sex/gender relations amongst staff in public libraries who have taken part in projects related to information technology. This is done through e-mail surveys and telephone interviews with staff who have participated in the development of the two library websites Mina bibliotek and Biblioteket.se regarding their experiences. The theoretical basis for the analysis is two gender theoretical perspectives with reference to technology. The first perspective is represented by Yvonne Hirdman?s theory concerning the gender system, in which women and men are kept apart and in which there is always a hierarchy where men are higher up, and Hanna Westberg-Wohlgemuth?s theory concerning sex marking of job-tasks.
