Research on Nursery History has a wide range of sources at its disposal. We must still investigate documents kept in professional colleges, as they are an accurate reflection of care and caregiver in the period of scientific development of the discipline. In this paper we shall describe the process of reorganization in the archive of the Nursery College in Huelva, as well as the situation of most Spanish nursery archives. Their classification aims to serve the College administration, which generates them, as well as the professionals and research, cultural diffusion and the reconstruction of this period of Nursery History.
