This is a reflection about the librarian's field of activity, which, based on the concept proposed by the French sociologist Pierre Bourdieu, considers that the field of activity for that professional, as well as for any other, presupposes, first of all, the perception that each profession is related to a knowledge, to a "know how to do, and also, to a "make someone know. We further present some reflections about the history of Library Science and bibliotherapy as work fields for the librarian. Bibliotherapy is understood as a reading practice that uses verbal and non-verbal texts to help in the treatment of people going through physical or mental diseases, or/and also, facing crisis or difficulties, in times of exclusion, social integration, distance from family members, communication, among others.
