The aim of this bachelor's thesis is to gain a deeper understanding of the subject which is about children's librarians and how they look at their professional identity when it comes to the work they do with bi- and multilingual children. This comes mainly from what we have read in earlier publications that exists in the subject as a whole. The analytical framework for the thesis is based upon Anders Ørom and Treine Schreibers professional identities written in the 1990's. The method for the thesis is made up of six semistructured interviews with children's librarians. The main results we got out of this thesis are that all of the professional identities could be found in the respondents for this study. We also found that several of the identities coexisted in parallel within the respondents.
