The aim with this thesis is to investigate how librarians experience communication with children in reference interviews. In today’s interactive community it is meaningful to study how children communicate with the librarian in virtual reference interview as well as in ordinary reference interviews in physical libraries. Focus has been on finding out what children ask about and how they are asking in virtual reference interviews and in ordinary reference interviews, what type of information needs the children have. The study also focuses on which barriers there can be in reference interviews. Empirical data has been collected by interviewing librarians who work in physical libraries and librarians who work with virtual reference interviews. The method used is qualitative interviews. The transcriptions were analyzed using Höglund’s and Persson’s theory about information needs and Buckland’s theory about barriers in information seeking. The findings show that the children’s own questions represent a subjective information need and the questions that children ask that come from school represents an objective information need. There are both similarities and differences between face to face and virtual reference interviews. The main differences are that the nonverbal communication is lost in the virtual reference interview and that the children are more anonymous in the virtual reference interview and therefore ask more private questions.
